    Hi,

    If the Q&A procedure didn't work, please let me know if you have a license that was purchased separately or one that came with the computer.

    Thanks.

    After a reset, Windows often reactivates automatically if the device already has a valid digital license. First check the activation state:

    1. Open Start > Settings > System > Activation on Windows 11, or Start > Settings > Update & Security > Activation on Windows 10.
    2. Review the message shown there.

    If the device shows Windows is not activated, use the path that matches the situation:

    1. Previously activated device, no major hardware change
      • Make sure the PC is connected to the internet.
      • If available, run Troubleshoot from the Activation page.
      • The Activation troubleshooter requires an internet connection, admin sign-in, and on Windows 10 it is available only if the copy is not activated.
    2. A significant hardware change happened, such as a motherboard replacement
      • A digital license is associated with the device hardware.
      • Open the Activation page and select Troubleshoot.
      • If the troubleshooter cannot fix it, use the reactivate after a hardware change option if it appears.
      • This works when the same Microsoft account was linked to the digital license before the hardware change.
    3. This is the first time Windows was installed on this PC, or no valid license is found
      • Enter a valid 25-character product key from Activation > Change product key.
      • If there is no product key, buy a digital license from Activation > Go to Microsoft Store.
    4. Need to confirm whether the license is linked to a Microsoft account
      • On the Activation page, look for one of these states:
        • Windows is activated with a digital license linked to your Microsoft account
        • Windows is activated with a digital license
        • Windows is not activated
      • If the license is linked to the Microsoft account, reactivation after hardware change is supported through the troubleshooter.

    If the troubleshooter does not resolve it, use the Windows activation error help page or contact customer support.
