I've got a Windows XP computer I upgraded to Windows 7. Didn't like the sound of Windows 8. I'm not sure if I should try getting it to run Windows 10, which it likely could.

It'd be much simpler if they just improved the old system to remove the bugs and loopholes with as few changes as possible, especially the cosmetic ones.

I could understand if it was a matter of cynically making us buy new versions, but when they allow free upgrades it seems a bit pointless, change for the sale of change.
