Microsoft has closed a loophole that allowed users to activate Windows 11 using older keys from Windows 7.
This comes after the company announced that it would no longer allow Windows 7 and Windows 8 keys to be used to activate Windows 11 a few months ago.
Previously, users could exploit a vulnerability that allowed them to upgrade from Windows 7 or 8 to Windows 10 and 11 without paying. However, Microsoft has now patched this vulnerability, and Windows 7 keys can no longer be used to activate Windows 11.
This change will not affect users who have already upgraded to Windows 11 using a Windows 7 key. However, any new installations of Windows 11 will require a valid Windows 11 key.
