User Guides Activating Windows on a refurbished PC

I've bought a refurbished Mini PC from Bharati Systems. It came pre-installed with Windows 10 Pro. I used power shell to display the license key as I was planning to install a fresh copy of Tiny10 Windows.

After installing Tiny10 in settings the version of windows is showing 10 Enterprise LTS. It was showing an error that stated it could not connect to the organizations server for activation. How to I use the license key that they gave me in the first place instead of the enterprise one which I don't have?
 
Don't install TinyShit or whatever you're trying to do.
Install the from the genuine installation image from Microsoft.

You can only install Win 10 Pro if you want to use your key.
