We currently run wsus 3.1 on a Windows 2008 Server. Our WSUS service is set to automatically download updates direct from MS. I've noticed we still haven't received Vista Service Pack 2 as an update, has it been released via Windows Update?
We have a few Vista machines here and i'm hoping to get the onto SP2 soon. I've had a play around and our wsus server seems to be up to date.
