I could not disagree more about downgrading to Windows 10.
Microsoft has been hostile toward PC gaming for years now, but it is getting desperate now, and I believe this is in large part because it realizes that manufacturing consoles may cease to be economically feasible in the near future. So after everything Microsoft has done over the last 10 years to drive PC gamers to the XBox, it is now trying to make PC gaming indistinguishable from a console, even mobile, experience.
Windows 10 has reprehensible BigBroTM Functionality: Both Microsoft and the goverment are keeping you safe, and also making sure you don't do anything stupid, like for instance decide which updates to install, and when.
The writing is on the wall. There is no reason to use Windows 10 when Windows 7 works perfectly well, and for now, works much better for games.
Stick to Windows 7 until the choice is either Windows 10 or no new games.
