Linking your device to a Windows Store app
Now that Windows 8 has hit the marketplace, more partners are realizing the potential of Windows Store apps that can be connected to devices, known as Windows Store device apps. Although the device app experience is simple and seamless for end customers, the process for device makers to create these linkages requires keen attention to detail. We're finding that metadata submissions for device apps often are failing because of minor issues.
The white paper "Windows Store Device App Lifecycle" details the process. It describes the .xml files that are needed to make the linkage, how to test the app and .xml files, and how to submit packages properly.
Dual-booting your PC
Want to try Windows 8, but need to keep Windows 7 or Windows XP handy? Here are a few tips to boot two versions of Windows on the same PC.
Install from older to newer, when possible
Typically, if you're starting from scratch, install the older version of Windows first, and then install the newer version. This generally makes it easier for Windows to set up the boot files.
Back up your data
If you already have an older version of Windows installed, back up your existing data. We're talking about formatting partitions. Better to be safe than sorry.
Make space for the new version of Windows
If your hard drive has enough space, you may be able to shrink the size of the Windows partition to make room for the new version of Windows.
If you're installing Windows over an existing partition, or adding a second hard drive, format the partition. This step is optional, but it's helpful to make sure that there are no straggler files from a previous installation.
While you're setting up the partition, it's a good idea to label the partition. This also is optional, but it's helpful in the next step to identify the partition.
Install the new version of Windows
Boot the PC using the Windows installation DVD.
When you're asked where to install Windows, be sure to select the new partition that you've created. You don't want to wipe out the data on your original partition!
After installing the new version of Windows, you have the option to boot either the new or the old version of Windows.
Troubleshooting: The dual-boot menu doesn't appear
If this menu doesn't appear, you may need to add an entry in the boot files for the version of Windows that's not booting. This typically happens when you install an older version of Windows after a newer version of Windows, or you wipe out the active partition while upgrading.
Submit for Windows 8 hardware certification
Partners should continue to submit devices, systems, and drivers for Windows 8 certification by using the Windows Dev Center Hardware and Desktop Dashboard. Register or sign in using the Dashboard tab at the top of the Hardware area of the Windows Dev Center to submit Windows Hardware Certification Kit (HCK) packages, device metadata, and drivers for distribution, and to view telemetry reports for Windows 8 and other supported versions of Windows.

Windows driver doc updates
Although nearly all of our new driver development content was released at RTM in August, we've recently created a few new topics and made many hundreds of bug fixes. Most of our bug fixes were made in response to customer feedback. Thank you-and keep it coming!
These updates to our Windows driver documentation were recently published on the Windows Dev Center:
Tools and tests
You can run these tests to test your driver and device on a target (or test) computer. You can run these tests from Microsoft Visual Studio or from the command prompt window.
The primary update to the sensors documentation entailed adding tables to the programming guide that describe the recommended Current Report Interval (CRI) and Change Sensitivity (CS) for the six sensors found on the tablet platform:

What's new in blogs for hardware and driver developers
New from NVIDIA: GeForce GTX 650 Ti - Big Power at a Small Price
Extreme Windows Blog, October 9, 2012
"NVIDIA has been hard at work this year rolling out a series of new video cards including the GeForce GTX 690, GeForce GTX 680, GeForce GTX 660 Ti, and many others. These new 600-series video cards are based on NVIDIA's latest architecture: Kepler. I recently spent some time running the GeForce GTX 660 Ti, and have been impressed with what that card can do with DirectX 11 games, and other graphics-intensive scenarios.
"Today NVIDIA launches the GeForce GTX 650 Ti, a new Kepler-based card that costs about ½ what the GeForce GTX 660 Ti costs, and still pumps out enough power to run the latest DirectX 11 games. With prices starting at $149.00, cards based on the GeForce GTX 650 Ti chipset will offer great bang for the buck."

"The companies said they will work together to come up with business solutions that use Windows 8 tablets on NTT DoCoMo's LTE network. While specific details are still scarce, the partnership will include joint sales and promotions, as well as the joint development of products for corporate customers."
Windows 8, the post-PC world, and Linux: Microsoft will prevail
Ars Technica, October 31, 2012
"Since the very first reveal of Windows 8, some critics have called the operating system a fatal move for Microsoft. They call it a blunder so large in its abandonment of Windows' heritage that it has created an opportunity for other operating systems to rise up and seize large portions of Windows' customer base in the consumer and enterprise markets. Others see Windows 8 as a sign that Microsoft is grasping for relevance in a world where Windows and the PC itself are waning. In this view, the once-mighty 'Wintel' platform is already dead-it just doesn't know it yet.
"Both sets of critics are wrong-or, at best, only half right. Windows 8 does create a huge opportunity for another desktop operating system to finally achieve total domination of the desktop and laptop markets, but that operating system is Windows 7. Sure, Windows 8 won't take the crown itself. But it has a slew of features that at least make its next major revision the heir apparent, not just to the desktop world but to a much more complicated computing kingdom. Even if one argues that Windows 8 is a hot mess of a user experience, it's still breaking the trail for what comes next."
Windows 8: What you need to know about the new OS
CNET, accessed November 2, 2012
"Microsoft makes an aggressive, forward-thinking and bold statement for the future of PCs with Windows 8, and vast security and speed improvements more than justify the $40 upgrade price.
