    1. Check the current activation state: Start > Settings > System > Activation. The page will show whether Windows is activated, activated with a digital license, or not activated.
    2. If Windows is not activated, run the Activation troubleshooter:
      • Go to Start > Settings > System > Troubleshoot.
      • This option is available only when Windows is not activated.
      • Sign in as an administrator before running it.
      • Windows activation also requires an internet connection.
    3. If the troubleshooter shows an edition mismatch:
      • If there is a digital license for Windows 11 Pro but Windows 11 Home is installed, select Upgrade to Windows 11 Pro in the troubleshooter, then select Start upgrade.
      • If there is a digital license for Windows 11 Home but Windows 11 Pro is installed, Windows 11 Home must be installed instead. During setup, the product key step can be skipped if a digital license already exists, and Windows will activate after installation completes.
    4. If there is a digital license but it has not been activated, in the troubleshooter select Activate Windows, then select Activate.
    5. If the device recently had a significant hardware change, such as a motherboard replacement, Windows may no longer find a matching digital license for the device. In that case, use the guidance for reactivating Windows after a hardware change.
    6. If phone or automated activation options are not shown on the Activation page, the Installation ID and Confirmation ID method can be used from an elevated Command Prompt:
      • Run SLMGR /dti to display the Installation ID.
      • Go to the Product Activation Portal and submit the Installation ID to get the Confirmation ID.
      • Run SLMGR /atp <enter your Confirmation ID> to activate.
      • Run SLMGR /dli to verify activation.
    7. If none of these steps work, use the activation error help page or contact support.

    1

    What happened on your PC before Windows was no longer activated.

    2

    Where did you get your Windows licence was that pre-installed on the PC or did you purchase a full retail Windows licence from Microsoft or from a 3rd party retailer, and if so, do you have the product key?

    Or is your Windows licence based on a previous Windows 7 or 8 licence?

    2

    Click your Start Button, type cmd then right click Command Prompt and choose 'Run as Administrator'

    Run or paste this command and hit Enter:

    slmgr.vbs /dlv

    Please post a screenshot of the resulting dialog
