Who is WSUS intended for?
WSUS is intended for Windows XP SP3, Windows Vista, and Windows 7 desktop computers that are members of the windows.uwyo.edu (UWYO) domain, with a few exceptions. When specific conditions are met, Automatic Updates may reboot a computer; therefore, a computer that provides a service that must be available 24×7 without interruption should not participate in this program. Computers that do not participate in WSUS should be updated manually on a regular basis using Microsoft’s update utilities.
