When you do patch Tuesday or out of cycle Window Updates, it creates a Restore Point "Software Distribution Service 3.0".If you have a problematic issue you can restore back before the update.
I would do it on ver 7.0.483.000 just to see if it would work.Work every time.Version 8.0.059 and this current version 8.0.298 system restore doesn't work.I sent ticket to tech support in both versions.
Got a case number for 8..0.059, but never got an answer.Maybe I'll get one for 8.0.298.
