If you have a licence version of Windows 7 you can still upgrade to Windows 10 by following the Windows 10 Update assistant. Make sure you have everything important backed up locally or online, you probably wont lose anything but why take the chance.

The people who think backups are important are the same people who have lost data in the past. You dont have to crawl into the fire to find that it’s hot.

Windows 7 to 10 or 11, upgrade still free
