Keep updates only in WSUS
Allow Windows Updates to be managed through SCCM but allow users to pull the actual files from WSUS.
In smaller environments why must I download the updates on the WSUS server than have the update sync down to the SCCM server forcing me to put 60 gig worth of updates in 2 places. This should be an option.
Tom, when used by ConfigMgr WSUS does not download updates content. At least, it should be. If it is then you have a mis-configuration somewhere along the line.
That being said, ConfigMgr _will_ store the content twice by design. First in the source folder for your (update) deployment packages and then again in the content library. The later is single-instance-storage but it's at the file level so you aren't going to gain much, if anything, with updates.
