How to upgrade from Windows 10 Home Windows 10 Professional without reinstalling

Going from a version of Windows 10 Home to a version of Windows 10 Professional is not as complicated as you might think. If you imagined a complete installation of the system to switch from one version to another, you were wrong.

Microsoft did it right. Upgrading a Windows 10 Home to a Windows 10 Professional is done by simply changing the product key saved in the system settings. You will therefore only have to buy a Windows 10 Professional product key that you will enter instead of the one already present on your machine.
