Quit Filtering out Windows 10 and Office 365 Client Updates from the All Software Updates node
The All Software Updates node should be just what it says - ALL SOFTWARE UPDATES.
However, since the addition of the Windows 10 and Office 365 servicing nodes, the All Software Updates node no longer includes Windows 10 and Office 365 updates. This is confusing and unnecessary behavior IMO.
It also makes the process to add these updates to the same SUGs as other updates more work as you can't query them all in the same pane. You have to query and add all non Windows 10 and non Office 365 Client updates to the SUG, then go to the servicing nodes to add any additional Windows 10 and Office 365 Client updates.
