Good you found it, but for anyone else interested, the github link is in the second post.

It’s not actually that AskWoody poster’s app, that was just a walkthrough on usage; thought maybe it was the one you were looking for, as WuMgr and the Windows Update MiniTool mentioned above are the two recommendations most people will get (on the non-enterprise side, perhaps).

Hopefully you figure it out, one way or another!
