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.
No clue. I’m still on 10 and I always run o&o shutup and other tools after a fresh install. I don’t get ads and such. But hopefully someone else can tell you more about 11 specifically.
