I have a Windows 7 installation disk. It works just fine. We have one laptop that has a newer version of the Windows. Don’t use it much.
I have two Windows 10, and two Windows 7. Have been trying to like 10, but don’t. (For some reason, Win 10 won’t open some .jpg files that Win 7 will.)
I’m gonna stick the two Win 10s on a shelf and go back to Win 7.
