Everyone on Windows 7 or 8 or 8.1, you can do a free upgrade legally to Windows 10, until July 2016 I think.

IF you make a backup or image of your old OS, you can just restore it back to your previous version.

Eventually, you will have to upgrade or do a clean install of Windows 10, depending on your work or purpose or whatever.

If you've previously upgraded, your Windows 10 clean install will be free, legally, tied to your computer. (unless you change motherboards or something.)
