Win10 Home to original Pro

Used an image of a Win10 Home laptop to copy programs/settings to a desktop pc.

Laptop had Home, desktop PC had license for Pro.

Needed to change desktop PC to Pro so people could Remote Desktop into it.

Variation from

Change Product Key from the System Control Panel (there’s an identical button on the Activation page in Settings).

Enter the default Windows 10 Pro product key:


That signals to Windows that we want  to upgrade from Home to Pro,

Click Start Upgrade, and after a few minutes, the system restarts. When connected to the Internet, the Windows activation process checks the hardware against Microsoft’s servers. Because this hardware was already recorded with a digital entitlement to Windows 10 Pro, it was activated immediately, without the need to enter a product key.
