Windows and Workstation licenses cannot be activated or fixed from here. For activation after a hardware change, only the documented options are available.

For Windows 10/11 Pro after a motherboard or other significant hardware change:

1. Try reactivating with the existing product key:
   • Select Start > Settings >
     • On Windows 10: Update & Security > Activation
     • On Windows 11: System > Activation
   • Select Change product key and enter the 25‑character key previously used on this device.
2. If the device had a digital license linked to a Microsoft account before the hardware change, use the Activation troubleshooter:
   • Go to the same Activation page.
   • Select Troubleshoot.
   • If offered, select the option to reactivate after a hardware change and follow the steps. For more detail, see Reactivating Windows after a hardware change from the documentation.
3. If Windows originally came preinstalled (OEM) and the motherboard was replaced by the manufacturer, it should reactivate automatically. If not, use any Certificate of Authenticity (COA) card provided with a 25‑character key:
   • On the Activation page, select Change product key.
   • Enter the key from the COA and complete activation.
4. If Windows came preinstalled and the motherboard was replaced by someone other than the OEM, or if no valid product key/digital license is available, a new license may be required:
   • On the Activation page, select Go to Microsoft Store to purchase a new Windows license.

If activation still fails (for example with errors 0xC004F211 or 0xC004F213) and none of the above options work, direct assistance from Microsoft customer support is required. Use the official support contact channel referenced in the documentation to continue the existing case or open a new one.

Workstation (non‑Windows) activation is not covered in the provided material; only the vendor’s official support can complete or correct that activation.
