In this article, learn how to quickly and directly downgrade from Windows 10 Enterprise to Windows 10 Pro without losing anything, having to clean install, or restart the computer.
Prior to Windows 10, the upgrade from the Pro to Enterprise edition required a complete wipe and reinstallation (clean install) of the OS. In Windows 10, Microsoft enabled bit-less edition upgrade from Pro to Enterprise. This means all the features are on the device already and the upgrade to Enterprise edition can be performed by changing the product key rather than having to download and deploy a new image. However, doing this required a reboot to complete. Microsoft heard a lot of feedback about having to reboot to complete the upgrade so starting with build 14352, a reboot is no longer required when upgrading from the Pro to Enterprise edition.
Luckily, it’s just as easy to downgrade from Windows 10 Enterprise back to Windows 10 Pro.
How to Downgrade from Windows 10 Enterprise to Windows 10 Pro
