Upgrade from Windows 10 Home to Pro using this product key
If you’re running Wi10 Home and want to know whether it’s worth moving on to W10 Pro, there’s a straightforward way of switching between the two versions of Ms’s latest operating system.
All you need to do is swap your current W10 Home product key for the default W 10 Pro one which Ms has made available to all users.
On the Ms Community Forums, Charles of Ms says:
As you can see from the above, while this will upgrade your copy of W10 Home to Pro, what it won’t do is activate it. If you decide you like the Pro version, you will need your own product key to activate the OS and use it permanently.
To switch product keys, open Settings and go to Update & security > Activation > Change Product key. Enter the product key from Ms(VK7JG-NPHTM-C97JM-9MPGT-3V66T) in the space provided. The upgrade process takes quite a while to complete so be patient.
If you want to buy a key for W10 Pro, go the Activation page in Settings and click the Go to Store button.
