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.
Probably blocks the MAS activation scripts from working too.
Sure enough, on their site:
Note: Microsoft servers are currently rejecting HWID activation requests when activating through MAS, we’re checking what’s going on now. Use the KMS38 activation option for now.
Wow, what a timing, just discovered MAS last month and used it last week. Was truly nice and easy, and I liked the technical explanations on their website.
