Fixing WSUS for all the various reasons.

So you cloned a PC and it has the same WSUS GUID. Sysprep didn't help.
Or you put a volume license onto an OEM, and now WSUS fails.

Whatever the reason, here is the batch file to fix it.


net stop wuauserv
rem Transflo depends on BITS and must be stopped first
net stop "TRANSFLO Client Agent Service"
@rem one known dependent service. Add others you know of.
net stop "Background Intelligent Transfer Service"

@rem Make sure the proper GPOs are applied
gpupdate

@rem re register services that may be broken
