I still use Windows 7, with my Skylake and Sandy Bridge. It works great still. I don't trust Microsoft anymore. With Windows 10, they crossed a line. I might have to upgrade to it one day, but I feel less secure with it than Windows 7. I don't worry about hackers. I worry about Microsoft being in bed with government and marketers. A hardware and a software firewall and antivirus do well enough against hackers. Those things won't stop Microsoft from abusing the many data connections back home to Microsoft. They'll look benign. It would feel more like an Orwellian Telescreen to me.
Games run fine, unless they require software that Microsoft refuses to provide for Windows 7. I HATE that means of forcing upgrades. How dishonest. It's too bad they won't ever have competition. That would require court orders of sharing their code to allow compatibility. People will stick with the OS that runs the software they like.
