How to fix Windows 10 (0xC004F050) error code
The (0xC004F050) error code usually means the edition of a Windows 10 OEM key does not match the edition of Windows 10 that is installed on your PC.
Check your Windows 10 edition
In the Windows Search Bar type in “Activation Settings”, hit enter to open the Activation window.
Your installed edition is shown at the top of the window (highlighted in red below).
If the installed Windows 10 edition does not match the edition of your Windows 10 OEM key, this is what is causing the (0xC004F050) error code.
Fresh Windows 10 install
As an OEM key is licensed for system builders doing a fresh Windows 10 install on new hardware, one solution is to do a fresh Windows 10 install.
Buy a matching key
Alternatively you can purchase a key that matches the Windows 0 1 edition you already have installed on your PC.
