Win 11 digital activation lost by Microsoft

The error code 0xC004F213 suggests that the product key is not available, which can happen if the activation data that identifies your PC to Microsoft has been erased, particularly after a clean install where all partitions were wiped.

Here are some steps you can follow to try to resolve this activation issue:

1. Verify Your Microsoft Account: Make sure you are signed in with the same Microsoft account that was linked to your digital license. This can sometimes help restore your activation status.
2. Run the Activation Troubleshooter: Navigate to Settings > Update & Security > Activation and look for the Troubleshoot option. This tool may automatically fix the activation problem.
3. Use Command Prompt for Activation: Open Command Prompt as an administrator and execute the following command to force an online activation attempt:

      slmgr.vbs /ato
   

4. Reinstall Windows 10: If the previous steps do not resolve the issue, consider reinstalling Windows 10 first. After a successful activation of Windows 10, you can then upgrade to Windows 11 again, which may help retain the digital license.
5. Seek Microsoft Support: If you continue to experience difficulties, try reaching out through Microsoft's online support channels or forums, as phone support is no longer available.

If these steps do not work, you may need to look into obtaining a new product key for activation.

Hello,

How did you obtain your license initially?

Did it come with the device preinstalled, or did you purchase it?

If you purchased it, did you purchase from Microsoft, or from third party?

Is it originally a Win7/8 key?
