What causes error 0xC004B100?
The activation server determined that the computer could not be activated. Common triggers include hardware changes, expired KMS handshakes, blocked Microsoft licensing endpoints, and incomplete cumulative updates. The error is fixable without contacting Microsoft Support.
Step-by-step fix
Follow these steps in order. The whole process takes under two minutes.

If the error still appears
