Have recently built a couple of servers with Windows 10 pro and wanted to try Windows 10 pro N to see how it differs. I have however discovered that a normal Windows 10 pro license doesn’t work with Windows 10 Pro N. 

Is there anyway I can make this work? Or anywhere I can get just the Activation code for Pro N?

Windows 10 Pro N is for customers in Europe and lacks media related technologies. The product key for Windows 10 Pro vs Windows 10 Pro N are different.

The UK is in Europe, so it would apply to it too, but Microsoft also provides the non Windows 10 ‘N’ editions for customers who want it.

The company is required by law to provide Windows 10 N as an option.

Migrating from either Windows 10 N or non-N requires a clean install.

You can purchase a Windows 10 Pro N license and use the key to activate it if you have that edition installed.
