I have downloaded the WSUS 3.0 SP2 from http://support.microsoft.com/kb/972455. I have WSUS 3.0 SP1 which is installed already on the SCE2007 on 2003 server standard with 64 editions so this means I have to download 64 bits WSUS 3.0 SP2? Also the WSUS 3.0 SP1 is installed in Administrative Tools so how can I install the WSUS 3.0 SP2 on the same location? After downloading WSUS 3.0 SP2, can I just run the setup.exe? Do I have to do anything to the previous WSUS 3.0 SP1? Do I have to stop any services on the SCE2007? Do I have to stop any services? Do i have to restart the SCE2007 server after updating to WSUS SP2? ThanksDeep Kumar
