I haven't had too many of the issues listed here so far. Only time I had crashes was when playing Fallout 4, and to be honest, that's *after* I modded the game all ways to high heaven. After taking many of the mods off, it ran better. Heck, it even ran Arkham Knight perfectly, literally 4 stutters in the entire time it took me to finish it and complete a number of AR challenges.
It even starts my computer up faster. So far I've only done the free upgrade from 7, it's not a clean install, and it took forever on 7. Yes, I do all the normal things (defrag, malware, paging file partition), not running an SSD, and seems to get up and running a lot quicker. Haven't tried anything from the Windows Store because screw that place. But for gaming and simple stuff, it's been more stress-free than I hoped.
One SERIOUS issue though: the Task Manager doesn't automatically come to the front. So Ctrl+Alt+Del doesn't always get you out of shit. So a word of advice, if you do a new install, open up that Task Manager, and set it to Always in Front, or else you're in for a bad time if things ever go sideways (could be anything, not necessarily OS related, heck even a bad CD read).
