It seems as if there should be more updates from WSUS...possibly its not receiving any?
It's set to get updates for Windows 7 and Windows Server 2008 R2. Critical updates, definition updates, security updates, update rollups, and updates.
Is it possible I set it up wrong somehow?
UPDATE: If I go to Win7 PC and click "Check online for updates from Microsoft Update", it finds a Definition Update for MSE, but not if I check for updates regularly using the WSUS settings ("You receive updates: Managed by your system administrator").
