You can no longer activate new Windows 11 builds with Windows 7 or 8 keys::Bad news for those planning to activate Windows 11 with a Windows 7 or 8/8.1 key: users noticed that the latest Windows 11 preview builds no longer allow activation with old license keys.
Still works with Windows 10 keys, however. Makes sense since Windows 8 and earlier are EOL now. Also, you don’t have to activate Windows if you don’t want to, it’ll just bug you occasionally.
