I see similar issues, but not sure of an answer. I upgraded my graphics card driver after reading some of these posts about Windows 10 frustration, to the drivers on the nVidia Website, and installed GeForce Experience, and so on. Amazingly, games, video and everything else run wonderfully. The fan doesn't constantly spin, and my computer is all around better for it. Next day, my computer's hard drive is whizzing away, presumably doing W10 updates. Lo and behold, it's replaced (rolled back) my graphics card driver to the old kludgy one that was causing the problem. Now it's back to FAN, stutter, and slow framerates on my 940m all over again. I can reinstall nVidia's drivers, but it will only last till I restart the computer. I am not aware of any way to block a specific update, what can I do?
UPDATE: Thank you all for your help. I think perhaps a little more information might be useful. I had this happen on an older Win7 machine, where Windows kept overriding the touchpad and keyboard drivers with its own. It was annoying then too, because it kept losing settings (like disable when USB mouse is connected). I had to reinstall that driver each time, because I didn't really want to disable ALL Windows Updates. I know that was silly, but it was 5 seconds of reinstalling rather than having the machine restart and rollback the driver each time. I recall that there used to be a way to block specific (device drivers) updates, is this no longer the case with Win8-10? I suppose worst case would be to disable all updates as some of you had suggested...and then manually install the ones I need. Sadly, I already had "Defer Updates" selected, so that hasn't seemed to help.
This is not a brand new machine, it's a 2015 Envy m7/5500U with a 940m+intel5500HD gfx.
