I've got a new tool, and its' called KB3125574, from Microsoft. Attached is a document I wrote about using it to revive an old system...if it'll work there, it'll work anywhere!
Warning; my draft was not properly labelled, and it HAS ERRORS. If you've tried my document, please read the new one. Not all is wine and roses (even if you're not concerned about the telemetry issues). I've updated some systems that have NO TRACE of the new KB3125574 having been installed, but the systems seem more stable. It's never the wonder tool I thought we were provided, is it?
