Yea. It wont be windows locking up but your overclock.
Yep, same here, despite having been stable for months if not years I had to put another +0.005v onto my vcore after installing 2004 as I was getting all sorts of random hangs / crashes etc. As soon as I dumped a little bit more voltage in, all the problems went away.
I've had it once before in exactly the same situation on another of the massive windows 10 updates but I can't remember which version number it was. Oddly some seem absoultely fine, but this is the second one that seemingly reduced my otherwise perfectly stable system to its knees.
