Its happened to me with 1 & I know a few others struck the same problem. I have notified MS when it happened I am on really good terms with their support if I strike the odd problem I let them know. All my updates are paused just waiting to see what wacky bugs appear before I attempt it on mine. I usually wait for a month or 2 before I do the annual 10 update. I got 1 I will test it on picked up a R9270OC for a stepsons I had crapvidia driver issues in it throttling it back. Its nothing special but the card I scored I from a Computer repair shop. 3 crapvidias 1 to go lol. I usually test 1 build at a time anyway I wanna get it it ready before he goes to electrical school. Just hoping I get the mongrel but going try a clean 10 then install card & drivers after. I am still running on 18.2.1 Drivers atm tho 2 other builds they arnt the best but Playing Vermintide 2 medium settings , other stepson playing GT5 & Beta testing.
