Below is what I am attempting within WSUS:
1) Search for “KB2982791” update
2) Select all updates
3) Right-click and select Approve…
4) For All Computers, select Approve for Removal and then Apply to Children
5) Click the OK button
6) Click the Close button for the Approval Progress window
NOTE: Some updates had results of “The select update does not support removal” but it still worked
7) Repeat for “KB2970228”, “KB2975719”, and “KB2975331”
The Windows Update client on computers with these updates have new updates with names that start with “(Uninstall:)” followed by the name of the update.
