Hello Support Team,

I am facing an issue with activating my Windows. I have tried to activate it, but I was unsuccessful. Please assist me in resolving this problem and provide me with the necessary guidance or activation steps if needed. I would appreciate your support and cooperation.

Best regards,

    Follow these steps to resolve most Windows 11 activation issues:

    1. Check activation status
      • Select Start > Settings > System > Activation.
      • Note any error code shown there (for example, 0x800704CF or 0xC004C060) and the activation message.
    2. Enter a valid product key (if you have one)
      • In Settings > System > Activation, select Change product key.
      • Enter the 25-character product key and complete activation.
      • If Windows shows error 0x800704CF, it means no valid license was found. Use a valid key from:
        • The confirmation email from the purchase.
        • The packaging that came with the device.
        • The Certificate of Authenticity (COA) label on the device.
    3. Use the Activation troubleshooter (if hardware changed)
      • If major hardware was changed (for example, motherboard replacement) and activation fails, run the Windows Activation troubleshooter from the Activation settings page.
      • Follow the prompts to reactivate. You might be asked to go through a reactivation process.
    4. Common activation error causes
      • Product key cannot be used to activate Windows (for example, blocked or wrong edition):
        • Enter a different product key or buy a new one.
      • Upgraded from an earlier Windows version and servers are busy:
        • Ensure Windows is fully updated, then select Activate again later.
    5. If online activation fails repeatedly
      • For Windows 10, activation can also be done by phone (Windows 11 uses similar mechanisms):
        • Press Windows logo key + R, type slui 4, and select OK.
        • Select the location, then call one of the listed phone numbers and follow the automated steps.
      • If activation still fails, contact Microsoft customer support from the activation error page or via the phone activation flow so support can review the license and reactivate if eligible.

    If an exact error code is provided, more targeted steps can be applied based on that specific error.

    1

    What happened on your PC before Windows was not 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?

    3

    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
