1. after WSUS installs an update must not it be removed from the list of updates from Windows Update?!
If it was installed successfully, then it should not be offered again (you must run a new check for updates through WU). The history won't list it, though.
2. how can i make WSUS download only the updates currently in the list of my Windows Update? not less and not more? exactly the same updates? or is there such a software instead of WSUS?
WSUSOU downloads the updates contained in the Microsoft catalog file WSUSSCN2.CAB. The real WSUS and the MSBA use the same catalog. Microsoft doesn't provide any other catalogs, and the WU list itself cannot be used either.
So you would have to use an Update collection. These contain more or even all updates, but are usually very large downloads and must be updated/refreshed every month.
3. i found Windows/wsusofflineupdate.log and the only Error lines are:
Thu 04/26/2012 17:44:40.42 - Error: Environment variable OS_NAME not set
Thu 04/26/2012 17:44:53.76 - Error: Invalid parameter. Usage: InstallOSUpdate <filename> [/selectoptions [/nobackup]] [/errorsaswarnings] [switches]
This is in fact an error that prevents WSUSOU from installing any update to this system. To post an excerpt from the FAQ (
