I do tech support in a school that still has Windows 7 on all PC's. These are old relics from 2008 and just this week I was informed we'll have to manage with them for a few more years. There's no way I can upgrade those things to Windows 10 not to mention we don't have the licenses. They can barely run 7. I'm thinking of throwing a user friendly Linux distro in those things. The principal liked the idea but I'm not sure the users will like it. But Windows 7 is becoming a liability.
