btw, afaik this bug doesnt exist on 32bit vista(i for one havent tried so cant confirm) , also is haswell worse than skylake is it safe to say so? i get a few issues here and there but they can all be fixed. Sound Issues are fixed through services , sometimes it would just run so slow due to superfetch not running but nothing major over here.
@win32 Great job on getting PM and WF working , idk if this info might be useful but in the future it could possibly help , nvidia drivers unofficially do work upto 372.70 , using 372.90 doesnt work , so that might be a great starting point for you? might be just a few missing functions or so since it does support w7 rtm
