If Windows 10 didn’t activate after upgrading from a licensed Windows 8.1:

  1. Use Activation Troubleshooter:
    Go to Settings > Update & Security > Activation, click Troubleshoot, and follow the prompts.
  2. Re-enter Windows 8.1 Key:
    Ensure your key is valid for the edition of Windows 10 installed. Use slmgr.vbs in Command Prompt (Admin) to input the key:
  3. bashslmgr.vbs /ipk <your-product-key>
  4. Contact Microsoft Support:
    Call Microsoft Activation Support to validate your key and manually activate your Windows.

These steps should resolve the activation issue.
