Acer Aspire laptop Restoring Windows11 license key.

Hi, guys, please, help me to clarify, can I restore Windows11 license key on my new Acer Aspire laptop by serial number or/and my payment receipt? I'm the first owner, but didn't find the license key on the laptop box.
The problem why I need it: I've got McCafe "protection", and the laptop CPU was overused. I tried to remove it in safe mode, but looks like the system is totally broken now. I can't log in with my credentials, tries to create a new user also failed.

What I already tried with no success:

searched for the license key in Registry
tried to get the license in CMD with different command.

Please, suggest.

Hi @MaxK700 it is not possible to get a Windows key on OEM products, that is, on Windows that are already pre-installed from the factory.

The product key is associated with the computer hardware and the first associated Microsoft account when it is first set up.

If what you want is to use that same license on the same computer, it will suffice to reinstall Windows with the same Microsoft account and it will be activated, but in cases where you want to use that license on a different computer, this will not be possible.

Thank you for participating in the Acer community.
Greetings.
