Linux works best for my PC (and perfect for my needs)
I have used Windows 10 (Pro Build 10586) and Windows is not perfect And After a while It got slowly (and bloated with apps. Programs -> Apps theory works here too + install 3rd party [ads] apps w/o permission)
I had clean install of Windows 7, but that got slow too (but not with linux as of now)
Currently using linux (Debian Based) AS MAIN OS, and yet I still can run Windows Programs (and most latest recently released games 😛 )
That's just my experience. Windows XP was and will be always the best :D
also rasperry pi uses linux (and limited Windows 10 IoT) why not to have tux and linux as emoji here?
Oh wait I might get ban for that. Oh well...
You know ReactOS, those guys are using Windows Kernel to create Windows like (Windows Based) Windows Alternative
