What if you lost the key?

By any chance, if you lose your product key then it is like an endgame. There is nothing much we can do to retrieve your key. And there is not much support from Microsoft too. The only possible way is to buy a new key to your system.

But, if you have linked your Microsoft account and your windows license, then you can simply log in with your Microsoft account to activate or re-activate your system.

You can reach the Microsoft support team for further assistance.
