The option is now only No, withoout the sub options, but it should do the same thing. I'm glad you pointed this out, as the windows update had changed this option back to yes for me
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.
