Yesterday, a fierce storm blew through the Internet targeting Windows 7, and the reports weren’t good. It’s been discovered that there is a severe enough issue that many are believing could result in a delayed Windows 7 release, although that would be tough to believe, since the RTM has just been released to MSDN subscribers today. According to Microsoft though, they see no issue, and if there is one, it’s not their fault.

The problem lies with the built-in disk-checker, “chkdsk”. When run with the /r switch, on a secondary drive, the program suffers from a major memory leak that effectively hogs all of your system RAM, and ultimately, gives you the infamous Blue Screen of Death. While many people have verified that this issue exists, Microsoft is adamant in stating that they’ve yet to experience the issue, and they believe if anything, it would be caused by hardware, not their software.

“While we appreciate the drama of ‘critical bug’ and then the pickup of ’showstopper’ that I’ve seen, we might take a step back and realize that this might not have that defcon level.” is what Microsoft’s Steven Sinofsky, president of the Windows Division, said, so it appears that they don’t believe it to be a major issue at this point. It’s also unknown whether or not this bug only exists in the RTM or not, because you’d imagine that if it has always existed, people would have discovered it long ago.

If anyone out there happens to be running any build of Windows 7, and you have a two-disk setup, and you are feeling a little brave, try out the chkdsk command, and see if the bug exists on your system. If your secondary drive is “E:”, then the proper command would be, “chkdsk /r e:”, without quotes.

On the Chris123NT’s blog, a user name FireRX, who appears to be a Microsoft MVP, said, “the chkdsk /r tool is not at fault here. It was simply a chipset controller issue. Please update [your] chipset drivers to the current driver from your motherboard manufacturer. I did mine, and this fixed the issue. Yes, it still uses a lot of physical memory, because [you're] checking for physical damage, and errors on the Harddrive [you're] testing… Again, there is no Bug.” FireRX also said he was sure a hotfix would be issued today.

Although GPGPU (general-purpose computing on GPUs) is growing in popularity, we’re still a little ways away from it becoming totally mainstream, and used by many. Over the course of the past year, though, NVIDIA is one company who has actively been pushing GPGPU, along with their CUDA technology, in order to get applications and scenarios in front of consumers to show them the benefits that their speedy graphics cards can offer.

One area where GPGPU can drastically improve performance is with video encoding, especially where filters are concerned. In some cases, the performance can increase upwards of 100 times over a CPU, and it’s for this reason that NVIDIA focuses on pushing the technology so hard. The company has just experienced a nice thumbs-up from a company called Lowry Digital, as well, as that company is the one which is responsible for enhancing the film footage of the Apollo 11 landing on the moon.

As you’d imagine, video footage from almost fifty years ago can’t hold a candle to today’s HD video, but even considering the time it was recorded, it still looks pretty bad given the circumstances. As you can see in the sample below, though, the image is drastically improved (there are more samples at the below link). In the  press release, it notes that on typical CPUs, each frame being dealt with would take upwards of 45 minutes to process, but with GPGPU, it takes seconds.

Maybe this is the kind of news that NVIDIA and GPGPU as a whole needs to get consumers excited about such technology, especially given that many people don’t realize they can do similar processing in their own homes.

“Lowry Digital’s restoration process has brought out details in the Apollo 11 videos that were never visible before,” said Andy Keane, general manager of the Tesla business unit at NVIDIA. “You can now see the faces of Neil Armstrong and Buzz Aldrin behind their visors, the stars on the U.S. flag when it is being raised and amazing details of the moon surface. We’re proud that NVIDIA has made such an important contribution to this historic project.”

One of the more touted features of Windows 7 has got to be the “Windows XP Mode”, which aims to tackle an issue that some found themselves with when moving to Windows Vista… incompatibility. With Windows XP, compatibilities existed, but they usually weren’t a major issue. Vista was the stark opposite though, with many peripherals simply not working, and applications as well. While XP Mode could only be considered an unbelievable workaround, it should do well to please anyone who’ll need to use it.

Last week, we posted an article taking an introductory look at virtualization, and how it works. Windows XP Mode uses the same technology, through Microsoft’s Windows Virtual PC application. With Windows 7 (and any current version of Windows for that matter), anyone can go and download the application for free. But if you want to use “Windows XP Mode” as Microsoft calls it, you’ll need to be using either the Professional or Ultimate version of 7. If you’re on Home Basic or Home Premium, you’ll have to provide your own copy of XP.

For those with Professional or Ultimate installations, you’re now able to download the RC version of Windows XP Mode and get to work right away. If all goes well, it should be simple, and everything should work as hoped. The RC features some updates worth noting, such as USB sharing. This means that your XP installation can utilize your USB devices such as printers and flash drives without issue.

To make use of the Windows XP Mode, you need a processor that supports either AMD’s “AMD-V” or Intel’s “Intel VT”. Most recent CPUs support these, but to make sure, you should look up your respective CPU model on the vendor’s website. To read more about Virtual PC and Windows XP Mode, check out Microsoft’s site here. If you happen to take this for a spin, post in our forums and let us know how you made out!

Windows XP Mode provides what we like to call that “last mile” compatibility technology for those cases when a Windows XP productivity application isn’t compatible with Windows 7. Users can run and launch Windows XP productivity applications in Windows XP Mode directly from a Windows 7 desktop. I also strongly recommend that customers install anti-malware and anti-virus software in Windows XP Mode so that Windows XP Mode environment is well protected.
