I think windows 7 is de best windows to play pc games on,why i think so,is because most games are compatibille with windows 7 rather than 8 or 10,besides yah never find any pop up error or anything of the sort,on which yah find on other windows,however you guys might have different views.....i wanna know what you guys think based on your experience n why...?
From personal experience, I would say that Windows 8.1 Pro is the best to game on. I've upgraded and downgraded from Windows 10 due to it's incompatibility issues and it's not really a stable release yet.
Windows 7 is based on windows XP which are booth stable OS to run for numerous needs (including gaming)
