Hello,

How did you obtain your license initially?

Did it come with the device preinstalled, or did you purchase it?

If you purchased it, did you purchase from Microsoft, or from third party?

Is it originally a Win7/8 key?

    After a motherboard replacement, Windows 11 often cannot find the original license because it is tied to the old hardware. Use the following steps depending on how Windows was originally activated.

    1. Check activation status and error code
      • Select Start > Settings > System > Activation.
      • Note any activation error code shown (for example 0xC004F211 or 0xC004F213 indicate hardware change/no key found).
    2. If there is a digital license linked to a Microsoft account
      • Sign in with an administrator account that uses the same Microsoft account previously linked to the license.
      • Go to Start > Settings > System > Activation.
      • If Windows is not activated, select Troubleshoot.
      • When the troubleshooter shows Windows can’t be activated on your device, select I changed hardware on this device recently.
      • Sign in with the connected Microsoft account if prompted.
      • From the list of devices linked to that account, select the one that corresponds to the current PC and check This is the device I’m using right now, then select Activate.
    3. If there is a product key (retail/OEM)
      • If the original manufacturer replaced the motherboard, activation may happen automatically. If not, and a COA card with a 25‑character key was provided, use that key.
      • Otherwise, use any valid Windows 10/11 product key previously used on this PC:
        • Start > Settings > System > Activation > Change product key.
        • Enter the 25‑character key and follow the prompts.
    4. If Windows came preinstalled and the motherboard was replaced
      • For many OEM preinstalled licenses, replacing the motherboard can require a new license. If activation fails with hardware‑change errors and there is no transferable retail key or digital license, a new Windows license may be required.
      • To purchase a new license from Microsoft: Start > Settings > System > Activation > Go to Microsoft Store.
    5. If the troubleshooter cannot reactivate
      • Ensure the same Microsoft account that originally held the digital license is being used.
      • If the device does not appear under that account or activation still fails, contact Microsoft customer support to request help reactivating or transferring the license after hardware change.
