Should I Buy an Upgrade Key for Windows 10 off eBay?

Episode 1594 (1:43:36)

Susan from O'Fallon, Illinois
Windows 10

Susan sees a Windows 10 update code for $5 on eBay. Is it legit? Leo says no! It's a scam and usually doesn't work.  And since Susan upgraded to Windows 10 and then downgraded, she can upgrade back to Windows 10 for free because she's already got an entitlement for her computer.  Go back to Windows 10, the time is right.
