Windows 10 Home upgrade to Pro by OEM
Hi, if you need update your preinstalled Windows to Pro version OEM .. it is little tricky but it is not impossible.
How do it ?
Go to Settings -> System -> Update -> Click to change product key
Enter this key : VK7JG-NPHTM-C97JM-9MPGT-3V66T and start update
After update is done now follow this steps again just insert your Pro OEM key.
Hope this help.
