REPLY this message for technical support.
if you see the error message----0xc004f050(this is most common error message)
please do the following steps.if it still does not work,please let us know.
1] Restart Windows 10 PC
It straight away worked for me because I realized that the key changed; it was not reflecting. When I visited Microsoft Store to buy a new key, it clearly displayed that the key has been activated. That made me realize that a simple restart can resolve this, and it did. When the reboot was complete, the Windows was activated with the new key, and I could see Windows 10 Enterprise.
2] Run Activation Troubleshooter
the Activation Troubleshooter appears only when there is a problem with activation. So now that you have the error Go to Settings > Update and Security > Activation. Click on the Troubleshoot button. Windows will start looking for solutions that can fix the problem. Strangely it did not work for me when I had the error, but its worth a try.
According to Microsoft, the error occurs at times when the activation servers get busy, or if you have upgraded using an offer. In either case, once the connection is made to the server, the key will be activated. If you do not want to wait, Windows 10 will automatically reactivate itself if you restart."
