Reminder: Windows Vista SP1 RC is about to expire

Microsoft today sent out a quick reminder to testers that the Windows Vista SP1 RC will soon expire. Although the official version of Windows Vista SP1 has been released for quite some time, some testers are still using the Release Candidate builds (any build number less than 6.0.6001.18000). These versions will become obsolete on June 30th along with Windows XP. The MU Team issued an announcement reminding users to upgrade or uninstall Vista SP1 RC before June 30th to avoid any potential issues.
