This is not just on WSUS machines. We do small business support and have customers who have the problem on standard 10 pro upgrades from 7 pro.
For all the people who say techs should test updates: this would be great, but Microsoft auto rolls out patches on 10 unless its a copy of windows10 enterprise.
This is of course stupid hence I tweeted today on #windows10updateisstupid It would be great if this got some support.
