WSUS purposely creates a WOUtemp account, which is like creating a new user.
So the account it creates, is the same as logging on to the Guest account, where the wall paper and all installed programs are there, but have no user settings. And the desktop and toolbars and quick launch etc, are all returned to factory new. Observe by checking what account you are on in Computer Properties or Network, showing not your normal account logged on.
This option happens when you check automatic restart in the Update Generator interface. Normally it is NOT checked.
However once ALL of the updates are installed it restarts and brings back your default user. The WOUtemp account can then be safely removed if there is left any traces of it.
It causes no immediate harm, they chose this method to be able to turn off any background programs that might interrupt the update process.
