I realize that Jim but why buy Windows 7 when I don't have any major problems with 8.1? It came with the machine free.
I guess I assumed that you still had your old copy of Windows 7.
I was thinking that like myself, some may still have their old windows 7, bought earlier.
I bought Windows 7 when it released. Since I build my own PCs now, I don't have a version "tied" to an OEM machine. So I could use it on any new machine I might buy that has Windows 8 on it, if I wanted to.
I use 8.1 as my main OS, with a few problems, but none major. I use 7 on my lappy, and as a dual boot with 8.1.
