Cable Cutters: Can 4G Hotspots Replace Cable Broadband?

I spent a couple of weeks connecting my home network with various 3G and 4G hotspots to find out whether they're up to the task.

I used to pay $60 per month for a bundle of TV service and broadband service from Comcast. I decided I didn’t want the TV part anymore, so I canceled it, leaving just the broadband. My new monthly bill: $60 per month.

Ever since then, I've yearned to cut that broadband cable, severing my association with Comcast altogether. I’ll admit that my cable broadband is fast and reliable, but it’s not a moveable feast--I get to enjoy those virtues only at home. Meanwhile I’m under contract with Sprint for another data plan, for service that I can take with me when I leave the house.

I’d love to ditch the home broadband and move to a mobile hotspot (preferably the one inside my phone) that connects all my devices no matter where I am. And I thought that maybe, just maybe, with the advent of 4G it might finally be time to cut the cable.

How I Tested

To see whether I could live without cable broadband, I spent the last two weeks using only a mobile hotspot to connect my home computer and other devices to the Internet. I used two 4G hotspots--Sprint’s Overdrive and the hotspot in my Sprint EVO 4G phone--and one 3G hotspot, the popular Novatel MiFi from Verizon.

I worked under the assumption that for a broadband device or service to truly replace the cable, it would have to connect multiple devices in the home. Mobile hotspots receive a cellular signal, and then create a Wi-Fi network to connect the devices nearby.

I ran a series of applications ranging from bandwidth-light to bandwidth-heavy to compare the performance of the cable service with that of the mobile-hotspot challengers. I read and sent e-mail messages, loaded graphics-heavy Web pages, downloaded MP3 files, watched high-definition video, video-chatted, and played online games.

Microsoft to wind down Windows 7 Family Pack sales by year's end

Computerworld - Sales of Microsoft's three-license Windows 7 Family Pack will end next week, according to online retailer Amazon.

The Family Pack gives consumers three upgrade licenses from Windows XP or Vista to Windows 7 Home Premium. When it started selling the $150 package in early October, Microsoft said it would offer the deal for a limited time, but did not set an end date.

On Friday, Amazon's page for the Family Pack told customers that the product would be "available to purchase until December 31, or while supplies last."

Amazon priced the Family Pack at $125.

If Amazon's stop date is accurate, Microsoft will have kept the Family Pack on the market for almost 13 weeks, more than twice as long as in 2009, when the company terminated sales after about six weeks.

Last year, customers got angry when Microsoft and retailers pulled the Family Pack from shelves without warning. Many were frustrated that they'd missed the offer, and some bloggers called the sudden disappearance a "dumb move" or pegged Microsoft as a Scrooge for dropping the deal before the holidays.

Microsoft set to unveil Windows version for tablets, reports say

It's not clear from the reports if the new ARM-based version of Windows would be based on Windows Embedded Compact

IDG News Service - Microsoft is set to announce a tablet version of Windows at the Consumer Electronics Show next month, according to reports by Bloomberg and the Wall Street Journal.

The reconfigured OS will run on processors from chipmaker ARM, according to the reports.

Microsoft already has one OS written for ARM chips, Windows CE, which is designed for use in embedded systems. The company in June said it has plans to release the next version of this OS, called Windows Embedded Compact 7, in early 2011.

This version of the OS will be targeted for devices such as set-top boxes and slates, company officials said..

Microsoft kills Office anti-piracy program

Computerworld - Microsoft last week killed an anti-piracy service that checked whether customers were running legal copies of Office, saying that the program had "served its purpose."

ZDNet blogger Ed Bott first reported on Microsoft's move after a tipster pointed him toward a support document on the company's site.

That Dec. 17 document simply noted that Office Genuine Advantage (OGA) "has been retired," but offered no explanation.

In an e-mail reply to questions today, a Microsoft spokeswoman added, "The program has served its purpose and thus we have decided to retire the program."

OGA, which debuted alongside Office XP in 2007, was Microsoft's way to separate counterfeit from legitimate copies of its popular suite. In 2006, Microsoft restricted Office template downloads to users running a legal edition of the application bundle, then upped the ante early in 2007 by requiring all users to validate their copy of Office with OGA to use the now-defunct Office Update site and service.

Say Goodbye to VGA in 5 Years

Intel and AMD announce that VGA will be phased out by 2015.

The VGA port, or Video Graphics Array, has been connecting monitors to computers since almost the birth ofZoom the computer. In recent years, displays and computers have begun to adapt the newer DisplayPort and HDMI technologies which allow for less space and power consumption and higher resolutions.

Intel and AMD have announced that they will stop support for VGA beginning in 2013 and expect the technology to die out by 2015, being replaced by DisplayPort and HDMI ports. We have already seen plenty of video cards stop supporting VGA and it is no surprise that the two giants of the computer world are beginning to do it as well. Getting rid of VGA means slimmer laptops that allow for a much more vibrant and clear high resolution display than the more than 20-year-old VGA.

Nick Knuppfer, Intel's spokesperson, told TechNewsWorld, "HDMI and DisplayPort are modern digital interfaces that support higher resolutions and screen sizes."

This move will result in a much quicker integration of DisplayPort and HDMI technologies which will lead to higher resolutions and modern interfaces on the displays of the future. Samsung, LG and Dell have already begun to integrate DisplayPort technology on their devices and are on-board with Intel and AMD's plans for the death of the VGA port.

New Hitachi HDD Could Lead to 4TB and 5TB

Hitachi's new 2.5-inch HDD crams 500 GB onto one platter.

ZoomThursday Hitachi Global Storage Technologies (Hitachi GST) announced its new 2.5-inch, 5,400 RPM Travelstar Z-series family of hard drives. According to the company, the 500 GB version offers the industry's highest capacity for a single-platter, 7-mm thick hard drive. This is accomplished by using the sixth-generation perpendicular magnetic recording (PMR) platters which feature a higher areal density (636Gb/inch2) than current hard drives.

With that said, Hitachi's new drive could pave the way to 3.5-inch HDD capacities higher than the current 3 TB limit. This would require using 3.5-inch platters with 636Gb/inch2 areal density, providing around 1 TB each. It's quite possible that within the next twelve months, we could see a 4-platter HDD offering a massive 4 TB capacity whereas a 5-platter HDD could offer 5 TB. For 2.5-inch form factor drives, consumers could see future models with 1 TB or 1.5 TB capacities using two and three platters.

As for Hitachi's new line of Travelstar Z5K500 drives, the series offers 500 GB, 320 GB and 250 GB models. Other feature include the previously reported 5,400 RPM spindle speed, a Serial ATA-300 interface and an 8 MB cache buffer. The drives also feature 1.8 watts read/write power, 0.55 watts low power idle, 5.5-ms average latency and 13-ms average read seek time.

Facebook's Zuckerberg vows to donate his wealth

Computerworld - Mark Zuckerberg, the billionaire behind Facebook, has pledged to part with a sizable chunk of his fortune for good causes.

Zuckerberg and 15 other billionaires signed on to the Giving Pledge, agreeing to donate the majority of their fortunes to charity. With the new names added to the list of charitable donors today, there now are 50 signatures, including AOL co-founder Steve Case, Microsoft co-founder Paul Allen and Larry Ellison, co-founder and CEO of Oracle.

Zuckerberg isn't the only one at Facebook to make the pledge. Dustin Moskovitz, who co-founded Facebook along with Zuckerberg, also took the pledge.

"People wait until late in their career to give back," Zuckerberg said in a statement. "But why wait when there is so much to be done? With a generation of younger folks who have thrived on the success of their companies, there is a big opportunity for many of us to give back earlier in our lifetime and see the impact of our philanthropic efforts."

Rumor: New Windows 8 64-bit UI Called ''Wind''

Windows 8 will supposedly have separate 32-bit and 64-bit interfaces, the latter dubbed as "Wind."

ZoomItalian-based website window8italia reports that Windows 8 will arrive with two separate interfaces, one for 32-bit and one for 64-bit. The latter version will be fully 3D and codenamed "Wind," requiring around 170 MB of dedicated video memory. Although "Wind" will reportedly exist in all copies of Windows 8, it will not be activated within the 32-bit version.

The news follows a recent discovery in Nvidia's Quadro 265 driver which specifically references a new kernel with the number 6.2-- Windows 7 is 6.1. The driver actually points to the 64-bit version of Windows 8 specifically as listed in the following:

; Nvidia Windows Vista / 7 / 8 (64 bit) Display INF file DiskID1 = "Nvidia Windows Vista / 7 / 8 (64 bit) Driver Library Installation Disk 1" Nvidia_Win8 = "Nvidia"

In addition to the 3D aspect, the 64-bit interface will reportedly be "fully dynamic" in that it will adapt to the user's habits. This includes the ability to speed up daily tasks by adapting shortcuts and icons to fit within different usage scenarios.

Is My Computer Dead?

This is a follow-up post with PC Won't Turn On post.

Today I managed to thoroughly test/troubleshoot my problematic computer. Here are what I’ve done:

  1. Remove motherboard from its casing. I wanted to make sure that there is no faulty grounding.
  2. Replace power supply unit, for isolation purposes.
  3. Remove HDD, RAM, Video card and tested the board with only CPU installed. I was expecting for RAM or video card error.
  4. Re-installed RAM, hoping that will give me video card error as its not yet installed.
  5. Re-installed video card, hoping that it will give me HDD error.
  6. Re-installed HDD, hoping it will boot properly.
  7. System speaker may also be faulty as it don’t make any sound.

I’ve tried each procedure twice in minimum but gave me no joy.

CPU fan and video card fan turns on when powered on but nothing happen. No leaking/bloated capacitors or simply no visual issues on motherboard and its peripherals.

I am now thinking of buying new computer as replacement.

Any suggestions or comments are highly appreciated.

Thanks!

Kingston Launches HyperX External USB 3.0 SSDs

If you're packing a USB 3.0 PC, then you likely have the need for speed. SSDs are clearly on our list of things that make our computers go faster, but those are already sitting happily in our internal SATA interfaces.
Kingston has a solution for those wanting to make their USB 3.0 fly, and that is with the just-made-official HyperX MAX external SSD. We first laid eyes on this product in its early stages back in June of this year during our tour of the Kingston factory, but now the product is finished and ready to ship in December.

The HyperX MAX 3.0 has a read speed of up to 195MB/sec., and a write speed of up to 160MB/sec., when paired with a USB 3.0 compatible device. It is also fully compatible with USB 2.0 devices, but the speed defaults back to USB 2.0 capability.

During Kingston's internal testing, a 10GB movie file was transferred in 1 minute, 12 seconds to the HyperX MAX 3.0 from a USB 3.0 system. On a USB 2.0 port on the same system, however, the transfer time increased to 5 minutes, 52 seconds.

PC Won't Turn On

My Windows 7 is acting weird today, it automatically shutdown while I am watching movie and it wont turn on when I tried to turn it on.

After re-seating the RAM it worked but during start up it turned off again. I turned it on again to no avail. So I re-seated the RAM again, it turned on until I finished on movie and I decided to turn it off, however this morning it won't turn on again and I'm now feeling that this take another re-seating to fix it.

I am now checking the hardware hoping to see any visible culprit.

Will be posting here for any development.

Any suggestion is highly appreciated.

Report: Dell ditches RIM for own WP7-based smartphone

IDG News Service - Dell is getting ready to move its 25,000 employees from BlackBerrys to its own Windows Phone 7-based smartphone, in preparation to the launch of its own migration service, The Wall Street Journal reported on Friday.

Dell employees will be given the upcoming Venue Pro, and the move will start next week. The company will then begin marketing a service to its business clients within two weeks aimed at helping them make a similar switch, according to the Journal.

Dell officials were not immediately available to comment.

The Venue Pro comes with a 4.1-inch display and a slide-out QWERTY keyboard.

The move will save Dell about 25% in mobile communication costs, primarily by eliminating the need for BlackBerry servers, Dell told the Journal.

Dell's decision to move away from RIM's smartphones to its own products doesn't come as a surprise to Leif-Olof Wallin, research vice president at Gartner.

"It would be kind of embarrassing to have your own sales staff walking around with a product from a competitor," said Wallin.

Seagate Says Future is Hybrid HDD, Not Pure SSD

Seagate's placing bets that people still want big, capacious HDDs, not just pure SSD speed.

When Steve Jobs debuted the new MacBook Air laptops last week, he said that the new products were what Apple felt were the future of the notebook. Likely he meant that laptops would be shipping with SSD rather than HDD storage.

We love SSDs and we think that they're quite at home inside mobile computing devices, but Seagate doesn't see the industry moving to full solid-state storage.

During a Seagate conference call, CEO Steve Luczo, said that he doesn't see SSDs as being the future. While that sounds funny coming from the leader of a storage company, remember that Seagate isn't heavily invested in SSD technology as some other companies who have feet deep in flash memory.

Luzco also said that he owns a previous-generation MacBook Air with an SSD, but he's frustrated at the lack of storage capacity inside the machine.

Gartner: The bell tolls for Windows XP

Computerworld - ORLANDO -- There are a number of IT trends users will see in coming years, but one that's expected to rise to the top will be the need to migrate off Windows XP and Office 2003 as the end of support nears.

In its annual list of the top 10 trends in infrastructure and operations, IT research firm Gartner detailed at its Symposium/ITExpo conference here the shrinking of data centers as users shift more work to cloud services, for one (see the full list below), but the standout issue for many will be the pending end-of-support dates for the Microsoft products.

Support for Window XP and Office 2003 ends in April 2014.

Although desktop operating system migration ranked No. 7 on the list, Gartner analyst David Cappuccio indicated that it would prove to be a more critical issue to some people.

"You may find yourself in a situation where these migrations become the dominant projects in your organizations over the next few months," Cappuccio said. "It's just a fact of life that we can only milk a cow for so long," he said, of the still widely used operating system.

Matt Holmes, systems manager for Johnson County Community College in Overland Park, Kan., said the Windows migration is "definitely" an issue.

"Over the summer we just had a round of 'firefighting' where we had a bunch of Windows XP SP2 machines that had to get upgraded to Service Pack 3 because of end-of-life support," said Holmes, who was at the conference. "I think it kind of snuck up on the desktop support folks."

The college plans to migrate to Windows 7, he said.

Scareware Mimics Microsoft Security Essentials

In PCMag's testing Microsoft Security Essentials 1.0 didn't rate as well as the best free antivirus products. Microsoft says that's OK, because their real aim is to get free antivirus into the hands of users around the world who have no protection at all. That's fine, but what if that copy of Microsoft Security Essentials is a total impostor?

Researchers at CyberDefender recently discovered a rogue antivirus threat that does a really impressive imitation of Microsoft Security Essentials. Click on the image above to see the impostor and the real McCoy. Can you tell which is which?

Here's a clue. If you were searching for "Dancing with the Stars" and later found Microsoft Security Essentials apparently running, you're looking at the fake. I know. In reality you'd be suspicious because you never installed the product, but not everyone is as discerning as you are. (OK, the lower image is the real one).

Dell's Convertible Inspiron Laptop is Also Genius

We're used to seeing convertible notebooks that turn into tablets, but this latest creation from Dell is like nothing we've seen before.

This is the Inspiron Duo. It's a 10-inch netbook that turns into a 10-inch tablet. However, the way the display swivels around is pretty different to what we're used to because it actually rotates inside the frame of the display's bezel.

Dell showed off the unique netbook at IDF yesterday, the slim Duo is powered by a dual core Intel Atom processor and runs Windows 7 Premium. The company revealed the netbook by introducing it as a Windows 7 tablet and gave a fairly run-of-the-mill media tablet demo by showing off music, photos and movies. However, they then shocked the audience by splitting it open to reveal that it was actually a laptop.

How To Fix Windows XP Freezes

You are about to complete your work but before hitting the save button your computer freezes and nothing else you can do but to reboot and loose your unsaved documents

Listed below are common causes of computer freezes and its recommended solution.


RAM (Memory)
  • All memory is being used by an application, so it takes time to process succeeding instructions. This is common on low memory system.
  • Faulty RAM
Recommended solution:
  • Terminate some of running applications to free some memory.
  • Test the RAM, use MEMTEST tool.
  • Replacement

Video
  • This usually causes freeze when there is a demand of video acceleration such as games, video (movie or editing), or graphics designing.
  • Faulty GPU (Graphics Processing Unit) will surely cause freezes. Windows 7 and Broken Video Card is one sample of a broken video card.
Recommended solution:
  • Visual check is needed, check GPU’s capacitors, chips, etc this part get busted over time.
  • Update the driver when needed.
  • Replacement

Device Drivers (incompatible device driver)
  • This is common issue. Especially for GPU drivers and will definitely cause computer freezes when not corrected.
  • Outdated drivers. It is known that latest driver may not be the best for you, it depend on your requirements. If your driver is not giving you problem then why update? Updates are needed if you’re installing new application and need feature from latest driver.
Recommended solution
  • Update Windows XP drivers as much as possible. Manufacturer's support/download site is the best option but if you get tired of searching then use a tool for search, download and install it for you.
  • Read driver's release notes before installation.

Bad Motherboard

  • Motherboard is considered one of the last parts of a computer to be replaced because replacing it is like buying new unit.
Recommended solution:
  • When you start encountering problem to your computer and you’ve isolated that none of your peripherals is causing it then it the time to consider the motherboard. Visual inspection is needed. Check bloated capacitors and chips or see if the whole board is bent which usually happen on old computers.
  • Send it to repair shop for troubleshooting.
  • Replacement.

Hard drive (HDD)
  • When you start experiencing slow access to your files, slow boot and freezes.
  • Knocking sounds from inside the computer.
Recommended solution:
  • Perform scandisk (chkdsk /r /f) to recover files on bad sectors.
  • Perform disk clean up to delete temporary and unwanted files.
  • Perform disk defragmentation.
  • Replacement

Software
  • Software conflict such as antivirus, firewall, anti-malware, and other tools.

Recommended solution:
  • Uninstallation of latest software installation.
  • Updating the software.
  • Uninstallation of unnecessary application.

Windows Registry
  • As being the database of all setup and configuration of windows machine when messed up will give unwanted result.

Recommended solution
  • Keep it clean, use registry cleaning tool. I use ccleaner for that which is impressive and most of all free!

My Computer Dont POST, Not after a Walk Break

Just this afternoon after 2 hours my computer wont POST - Power On Self Test.

I has been up for about 8 hours from morning till afternoon, then I decided to go for a 2 hour break, then when I opened it just simply don't POST.

Being an IT, here is what I've done and checked:
  1. Listen to any beep codes, its OK
  2. Opened the casing and remove HDD power not to corrupt it from turning it on and off.
  3. Removed RAM then powered it on hoping to hear any error beep code, no avail.
  4. Re-connected my VGA cable to CPU box, no avail.
after these 4 procedures I decided to go for a walk thinking of what may just happened and the reports I need to pass today...

Guess my walk break works, I've re-connected the VGA cable at the back of my monitor and its power adaptor and everything is back to normal like nothing happened.

OK may be I just tired or something but I am happy that I can now write it up and send my reports :)

Was thinking that I may have something to do with my windows xp drivers but thanks it is updated and nothing to worry about it.

Intel's 50Gbps Laser Light Beams Are the Future


Sharks with 50Gbps laser beams?

Someday in the future, we may look back on the technology we're using today and laugh that we were using electrons to carry data in and around computers.

Intel Corporation this week announced a research prototype representing the world's first silicon-based optical data connection with integrated lasers. The link can move data over longer distances and many times faster than today's copper technology; up to 50 gigabits of data per second. This is the equivalent of an entire HD movie being transmitted each second.



The transmitter chip is composed of four such lasers, whose light beams each travel into an optical modulator that encodes data onto them at 12.5Gbps. The four beams are then combined and output to a single optical fiber for a total data rate of 50Gbps. At the other end of the link, the receiver chip separates the four optical beams and directs them into photo detectors, which convert data back into electrical signals.

While telecommunications and other applications already use lasers to transmit information, current technologies are too expensive and bulky to be used for PC applications.

Today computer components are connected to each other using copper cables or traces on circuit boards. Due to the signal degradation that comes with using metals such as copper to transmit data, these cables have a limited maximum length. This limits the design of computers, forcing processors, memory and other components to be placed just inches from each other.

15 Things Every PC User Should Know

Think you know tech? If you don't have a handle on every single one of these 15 tech facts, habits, and efficiency tricks, you're not living up to your potential.

1. Don't double-click everything. Windows 101: Double-clicking is how you open items in Windows. It's not how you open links in your Web browser, click buttons in dialog boxes, or do pretty much anything else--and if you reflexively double-click, you might accidentally zip right past something important or submit a form twice. If you don't need this reminder yourself, chances are you know someone who does.

2. Use slashes and backslashes in the appropriate situations. Let's get it straight: / is a slash (or forward slash, if you must), and \ is a backslash. Backslashes are conventionally used for Windows file paths (C:\Program Files\Whatever), while slashes are used for Internet addresses (http://www.pcworld.com/howto.html).

3. Record the exact error message. When your PC crashes, it'll usually try to tell you why it is doing so--albeit with a string of numbers and letters that you won't understand. Write the message down in its entirety (or take a screenshot, if possible) so you can later plug it into Google or give it to your tech support agent. If your PC didn't provide an error message, go to Action Center (in the Control Panel) and see if it shows up under 'View archived messages' or 'View problems to report'.

4. Bring deleted files back from the dead. When you delete a file from your PC or memory card, you're not wiping it off the actual hard drive. Instead, you're simply removing the index information that tells your PC where the file is, at which point the PC is free to treat the part of your disk that contain that file as empty space that it can write something else to. If you've accidentally deleted something, undelete utilities such as Recuva can help you find those files again as long as you haven't already written over that file with something new.

Qualcomm to Ship Fastest Chips for Phone

Are you an Smartphone and Tablet user? Be happy! Qualcomm to ship fastest chips for phone.

Qualcomm will start shipping its fastest Snapdragon dual-core chip for smartphones and tablets in the fourth quarter, with devices possibly launching by the end of this year, the company said on Monday.

The company will ship the dual-core QSD8672 chip with CPU cores running at up to 1.5GHz, said Mark Frankel, vice president of product management for Qualcomm CDMA Technologies. The chip could go into smartphones, tablets and low-cost laptops, he said.

Frankel pegged the launch date for devices with the new chip for early next year, adding that aggressive vendors could launch products "by Christmas" -- or the fourth quarter -- this year, Frankel said.

The chip is a follow-up to the dual-core MSM8660 Snapdragon chip, which started shipping in the second quarter. The 8672 has a faster processor than 8660, which includes CPU cores running at 1.2GHz. The processor in the 8672 chip is based on an Arm design and will be manufactured using the 45-nanometer process.

The chip is similar to the 8660 design with a raft of improvements compared to its previous single-core chips, Frankel said. That should bring better power management and performance to devices, Frankel said.

Windows 7 Performance Booster

One thing I like with Windows 7 is its fast processing time compared to its predecessors Windows Vista and Windows XP. Yeah! I'm pressure you'll agree with me that it also faster than XP. But the good news this operating system can get even faster with simple tricks.

Learn how Windows 7 get faster.

1) Uninstall bloatware that came with your laptop or PC. Or even apps you installed but no longer want. Head to Control Panel | Programs | Uninstall a program and take the hatchet to anything, such as unwanted games or software, that you'll never need. Many programs will load processes at boot time and take up valuable RAM and CPU cycles. While you're in here, you can also click Turn Windows Features On or Off and scan the list to see if there's anything you don't use. You might also want to try out software utilities such as PCDecrapifier and Revo Uninstaller.

2) Limit start-up processes. In the Start button's search box, type MSCONFIG, then head to the Startup tab. You'll likely see a slew of apps, mostly for system support, but you'll be able to identify some that clearly aren't necessary. There's absolutely no need to have Google Update or even QuickTime running all the time, for example. Don't delete those that support your hardware or security, but anything blatantly nonproductive can go. You may have to check the program names online with a site like processlibrary.com to see what they are—they may even be malware. If you want to get more granular, run Microsoft's Autoruns utility.

3) Add more RAM. Windows 7 isn't as much of a hog as Vista, but if you're moving from XP, the memory requirements are greater.

4) Turn off search indexing. If you do a lot of searching, this won't appeal to you, as some searches will be slower. To turn off indexing, open the Indexing Options Control Panel window (if you just type "index" in the Start button search box, you'll see that choice at the top of the start menu), click Modify and remove locations being indexed and file types, too. If you want to leave search indexing on, but find that it occasionally slows you down, you can stop its process when you need extra speed. Right-click on Computer either in the Start menu or on the desktop, and choose Manage. Then double-click Services and Applications, then Services. Find Windows Search, and double-click on that. From this properties dialog, you can choose a Startup type of Manual or Disabled to have the process silent by default.

5) Defragment your hard drive. Your disk stores data in chunks wherever there's disk space, regardless of whether the space is contiguous for one file. Defragging tidies everything up and blocks a program's bits together so that the reader heads don't have to shuttle back and forth to read a whole executable or data file. Windows 7 comes with a built-in defragger that runs automatically at scheduled intervals, but if yours is set by default to run at a time when your PC is usually turned off, it won't get defragged. You can either change the scheduled time, or defrag on demand. Just type "defrag" in the Windows Start Menu search bar, and click on Disk Defragmenter. The version of the utility is improved in Windows 7, and shows more information about what's happening on your disk than Vista did.

There are 45 more tips to speed up your Windows 7 computer.

Speed Up Windows 7 - More!

Everybody may agree that windows 7 may be the fastest windows version available.
BUT it can be faster! yeah!

One of the main virtues of Windows 7 is its speed—especially when compared with its predecessor, Vista. But most people haven't experienced the 15-second boot for the operating system that Microsoft engineers were shooting for. And there are certainly times when Windows you'll still see that spinning blue donut. We can always hope that the upcoming Windows 7 SP1 will include some performance tweaks, but, in the meanwhile, there are plenty of things you can do to speed up your installation of Windows 7.

The problem with most "speed-up Windows 7" stories is that they tell you to turn off some of the operating system's more charming visual features. The first nine of my dozen tips show you ways you can speed up your Windows 7 system without compromising its appearance. For those who need even more speed or don't care about eye candy, I've listed three at the end that boost system performance at the expense of some visual effects.

Windows XP Downgrade Extended to 2020

Due to insisting public demand Microsoft announced the extension of Windows XP downgrade until 2020.

The company that I an working will benefit from this. The entire corporation is still using Windows XP SP3 and no incompatibility at all. Guess this is a big slash from IT budget.

Don't you think its too long - 2010?
One thing I like about this is we have time off sorting out new compute issues, windows driver issue, and other hardware incompatibility.

Read below news from Tomshardware.com

Another decade of Windows XP -- who's excited?!

While the consumer and enthusiast are now happily moving to Windows 7, businesses are still chugging along on Windows XP. This would present a problem for businesses buying and installing new computers in the workplace if not for the Windows XP downgrade program available to OEM Windows 7 Professional and Ultimate SKUs.

Originally, these downgrade rights were to disappear once Microsoft ships the first Service Pack in 2011, but upon the release of the SP1 beta, Microsoft announced that it would extend the XP downgrade period through to January 2020 for the Professional and January 2015 for the Ultimate edition (dates according to Computerworld).

"This will help maintain consistency for downgrade rights throughout the Windows 7 lifecycle," wrote Microsoft spokesman Brandon LeBlanc, in an entry on the company blog. "As a result, the OEM versions of Windows 7 Professional and Windows 7 Ultimate will continue to include downgrade rights to the similar versions of Windows Vista or Windows XP Professional. Going forward, businesses can continue to purchase new PCs and utilize end user downgrade rights to Windows XP or Windows Vista until they are ready to use Windows 7. Enabling such rights throughout the Windows 7 lifecycle will make it easier for customers as they plan deployments to Windows 7."

hal.dll Error

One computer in the office today got an hal.dll error when she open her computer. Being the IT in the room I was ask for help. First look I know that it is repairable by going to Recovery Console and replacing the missing file. But I was reluctant to repair it because I'm not hired as IT but a database consultant and I don't Windows XP install CD.

I advised my office mate to report it to our IT helpdesk. OK, so after few hours I saw her working on another workstation as her laptop (Dell Latitude d630) is diagnosed to have faulty HDD, to my surprised I've chatted our IT personnel to ask what happened. Our IT department is good, they've run Dell diagnostic tool which reported the said issue.

So her laptop is now waiting for Dell technician to replace the HDD, good that its still under warranty but sorry that she lost most of her files.

After few research I've found out that my bet of repairing it via recovery console is the best solution but this is provided that the HDD is healthy which is not my case.

BIOS to Die in 3 Years?

"MSI will begin its shift over to UEFI by the end of the year, with the industry expected to follow over the next three years.

Is the end of BIOS almost upon us? That's the current speculation, with the date of termination expected in the near future. According to an unnamed spokesperson for MSI, the motherboard manufacturer is making the shift over to point and click universal extensible firmware interface (UEFI) systems by Q4 2010/Q1 2011. The change is expected to become "widely adopted" within three years thereafter"

they say that current ROM size till not be enough for this new technology. I am thinking what how and what drivers will they use to run/recognize the I/Os

Dell Refuses Blame for Optiplex Problem

Dell is my choice of computer brand. Most of the company I worked with are into Dell. After sales support (hardware, software, drivers, technical) are one thing that I like about it.

We use dell optiplex, I was surprised when a read a news that this line of product has motherboard defects...

Dell on Thursday flatly denied that it shipped faulty computers back in 2003 and 2004, and again said that any problems its customers experienced with Dell OptiPlex desktops were due to an industry-wide problem with capacitors produced by Nichicon. "Dell did not knowingly ship faulty motherboards, and we worked directly with customers in situations where the issue occurred," Dell spokesman Lionel Menchaca wrote in a blog post. The issue stems from a 2007 lawsuit filed by Advanced Internet Technologies (AIT), which accused Dell of knowingly shipping faulty desktops and then reneging on a promise to provide extended warranty coverage. Though the case is more than three years old, it made headlines this week after documents in the case were unsealed and The New York Times picked up the story. Dell on Wednesday dismissed the issue as "old news" and said that the problem originated with a capacitor manufacturer, not with Dell.

Windows sigverif for System Integrity

Unsigned Windows Driver may hurt your system, yeah! Because it did not come from your vendor so warranty is out.

Windows sigverif (File Signature Verification) is a tool to verify/maintain the integrity of the system, critical files have been digitally signed so that any changes to these files can be quickly detected.

In simple words it will check what files are unsigned and report it to you for your action.

How to use it:
1. Go to Start >> Run type in sigverif hit enter. Sigverif windows will open.












2. Click “Start” to start scanning.

3. Unsigned files will be reported back to you. Mine are windows drivers.















Go ahead and verify your files.

SFC – System File Checker

Scan all protected system files and replaces incorrect versions with correct Microsoft versions.






Scan Options

/SCANNOW – Scan all protected system files immediately.

/SCANONCE – Scan all protected system files once at the next boot.

/SCANBOOT – Scan all protected system files at every boot.

/REVERT – Return scan to default setting.

/PIRGECACHE – Purges the files cache.

/CACHESIZE=x – Sets the file cache size.

/? – Display help at the command prompt.

How and when to use it?

After update that went wrong.

Windows update sometimes causes corruption of system files, yes it is!

After virus infection

No doubt it can ruin every file including system files.

After installing/updating windows driver that causes system error.

Digitally signed files/application are allowed to replace/update system files but this also causes system file corruption

Or simply everytime a system file has been corrupted.

This tool can be executed everytime you want so if you feel you need it then use it.
