For most computers, once the motherboard in your computer has been replaced, the replacement motherboard has a preinjected key in the motherboard firmware that automatically activates Windows.
In a few cases, for various reasons, this automatic activation process may fail and a replacement Service Product Key for Windows may be required to resolve the issue.

Note: In cases where a replacement motherboard does not have the preinjected key that automatically activates Windows, Dell tech support provides a Service Product Key for Windows.
No cause information is available.
If Windows fails to activate after a motherboard replacement, Contact Dell Tech Support and allow the agent to troubleshoot the issue.
