if none of this works and you're system works perfectly without the latest beta patch, don't install it, is all i can say, while most i mention above can repair your O/S it's not as good and never will be as good as a fresh install, which fixes 100% of any error, so at least the O/S is more stable and patched, before any games and software are installed, then at least you know it's software and not hardware that's not compatible etc if you then get a gaming error.
my test pc gets reinstalled every month, then again it gets some hammer, my gaming rigs, new and old get reinstalled around every 3 months or so, as soon as the latest version of windows comes out or a repacked version eg later build ISO, i download and reinstall and image a drive with that on to use on all my systems, so normally all my pc's are on windows 10.
Windows 10 Home Single Language 64-bit (10.0, Build 15063) (15063.rs2_release.170317-1834) is what im on now
Windows 10 (1709 RS3) "Fall Creators Update" Final 16299.15 is the latest version released to manufacturers on 17th Oct 2017
