The issues i had with W10Pro are only SLI and overlay related and also with some exotic drivers for specialized hardware.
The CTD can also be Crew related or Uplay. But the combination of the W10 OS and other programs is far from optimized and it feels indeed like a beta test sometimes.
W8.1 is far more stable, has better support and runs games a lot smoother as it was natively supported during a lot of game developments. W10 is not the same, despite what M$ tries to make you believe.
There is sometimes a little hesitation when opening windows and programs, that i have not seen in Vista, W7 or W8. Typical for monitoring what you do.
It must be the biggest spyware scam in the history of operating systems.
And if any "anonymous" hacker ever gets his hands on the source codes, they had it coming. They build in this risk.
Having said that, i won't uninstall W10 as it works well most of the times and i expect more updates like the recent huge W10 patch that had the size of a complete operating system and probably was a complete new version of W10.
If that kind of support continues, i see no issues using it for a long time.
If they want to monitor how we game, good for them, maybe they pick up a thing or two
