Upgrade for Windows 10
Upgrade for Windows 10
Hello, yes you can use the same Windows 7 Professional key on another PC after upgrading to Windows 10. Just make sure the hardware matches and the system meets the requirements.
Microsoft would refuse, yet occasionally the same W7 product key functions across multiple computers—even without being cracked. I purchased Windows 7 and successfully applied the same key to two different PCs, which actually worked (keep it secret from Microsoft).
