Starting this Tuesday (May 12th) we will release up to ten test updates to PCs running the Windows 7 RC in order to verify our ability to deliver and manage updating of Windows 7 in certain real-life scenarios. These updates do not deliver any new features or fixes. This is the second set of test updates we’ve released to test the updating mechanism for Windows 7 - the first set were released on February 24. For more information, see this post on the Microsoft Update Blog.

Starting February 24, we will be releasing up to 5 test updates to PCs running the Windows 7 Beta (Build 7000) via Windows Update. These updates allow us to test and verify our ability to deliver and manage the updating of Windows 7. We typically verify servicing scenarios during a beta.

Windows 7 Beta users will be notified that new updates are available beginning February 24 through Windows Update. Even if the user has Windows Update configured for automatic update – these test updates will not install automatically. Users will need to manually install the test updates through Windows Update.

These updates do not deliver new features or bug fixes. The test updates simply replace system files with the same version of the file currently on the system.

Again, thank you for helping test Windows 7. Your feedback is extremely valuable!
