WSUS Admins, Happy New Year!!


I wanted to provide some guidance on the prerequisite update (KB935509) for Windows Vista Service Pack 1 because it’s a little different than the typical content we release.  You may have read about on the Windows Vista team blog


This update, which will be released on Tuesday, is a prerequisite for installing Windows Vista Service Pack 1 on Windows Vista Ultimate and Enterprise editions.   Even if you don't plan on installing the service pack for awhile, you may still want to test and deploy this update.  Not only does it make improvements to the boot loader, but it's also required prior to installing the two upcoming prerequisites for SP1.  The two upcoming prerequisites will have an updated installer technology which will increase performance and reduce failures for the installation of updates, which are great improvements to make even if you choose to wait to deploy SP1. 


Deploying this update and one of the upcoming prerequisites will also eliminate one reboot once you are ready to deploy SP1, which will be available in the first quarter of 2008. In fact, we're distributing the update during this Tuesday's release  in an effort to reduce customer pain associated with multiple reboots.


To learn more about this specific update, see KB article number  KB935509.


One more thing, remember that you can find information on the content released through Windows Update and Microsoft Update from the following site:

 Thank you!
