WSUS Groups are used as target groups in Application Manager for WSUS. You can use existing WSUS groups, or create new groups.
To modify WSUS groups from the WSUS management console:
1. From the Windows Start menu, open Windows Server Update Services (wsus.msc).
2. Navigate to Options > All computers. You can see a list of your current WSUS groups, or create a new one by right-clicking All Computers and selecting Create new group.
