After updating my Windows 11 to 24H2, my Windows is no longer activated. I get the message "You need to activate Windows before you can personalize your PC". When I click on "Activate now", I get the error message "Windows reported that no product key was found on your device. Error code: 0xC004F213". What to do? My Windows was already activated.

Thank you.
You have OEM-COA-NSLP license, so you should have a sticker with the license key somewhere on the computer, look around and see if you can find it.
Once you find the key, you just need to go to Settings > System > Activation> Change product key, input it again and it will activate.
Screenshot is attached.
