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.
The answer is a resounding maybe. If you activated with a Microsoft account or if there’s a TPM chip, the chances of it still working increases. There are different kinds of licenses, but if it fails, there’s a better than not chance calling MS support and just telling them you had a hardware failure on your laptop and you need to reinstall, they’ll get you going. Not a guarantee though. And I’ll caveat and say this information is a couple years old (I don’t work in tech support anymore).
