Beginning February 24, Microsoft will be deploying up to five dummy updates for users of the Windows 7 Build 7000 beta. The packages contain identical replacements for current system files as the experiment is simply an effort to test Windows 7’s update infrastructure.

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.
