Solution 1. Activate  Windows 10

Windows activation error code 0xc004f050 may be caused by an upgrade. If you have upgraded your Windows form a lower version to a higher version, please use the default product key provided by Mircosoft (see image below).  Windows 10 will prompt you with a message “We couldn’t activate Windows,” just close it and then reactive it again using your product key. Please see below for the instructions. 

NOTE: If you recently change your motherboard/laptop, the product key that you have used from the previous motherboard/laptop will be useless. Because your product key will be tied up to the BIOS of the old motherboard/laptop. The only solution for this is to buy a new product key.
