Below is a quick rundown of all the goodies in the new Service Pack for Windows 2008 and Windows Vista.  Of course, SP2 includes all hotfixes and other updates post SP1, but unlike traditional methods, Windows Server 2008 SP2 and Windows Vista SP2 uses the same Service Pack executable, which makes it easier to deploy.

Although this update provides minimal changes, it’s always recommended to do a test rollout before deploying in full.
