The 0xC004F213 activation error can occur on both Windows 10 and Windows 11.
So the first place to start is to try logging into your Microsoft account.
If you purchased Windows using it, this may help to activate it on your machine.
If that doesnt work, then go to options and find the Activation section there.
There you will be able to drop your Windows license key and activate it manually.
Then you just need to enter that code into the Windows license activation field.
Microsofts activation servers recognize that the key has been used before, and therefore activation does not occur.
There are several basic ways to solve this problem.

Is it legal to use Windows activator programs?
you’ve got the option to also give a shot to use third-party applications to activate Windows.
However, you should realize they are not legal and may have viruses or tracking programs.
I do not recommend that you use such applications.
This can cause your system to malfunction or even crash and void your manufacturers warranty.
