It's only been two months since the last Intel driver was released in Windows Update on Win7. The GPU is supported just fine thanks.
Also, we build systems which run our application suite controlled by a custom control panel, and we have yet to manage to fully tame Win10's intrusiveness into the operator's workflow. Even if we do fully tame it, maybe the next version will change the number of things needing tamed. I'd use Windows Server instead, but it isn't supported by ASUS on desktop motherboards. We're in a dead end and seriously thinking about Linux at this point.
