    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.
