Windows 10 does have some issues on my computer after updates, causing instability on the machine, though not noticeable in any games. I've been able to fix them by updating drivers (interestingly, the last one that I had to update to fix it was the Realtek audio, which apparently was updated twice within a week, so either Windows was switching something that didn't play well, or Realtek's first update wasn't all they hoped it would be. I'm not sure why Windows 10 seems to cause more problems with drivers than previous versions, but I eventually installed one of those driver update programs. If you don't trust the drivers from the program, you can make a note of what drivers it says need updating and go to the appropriate vendor site instead.
