SOLVED: VIDEO: How to Easily Downgrade From Windows 10 Enterprise to Windows 10 Professional

In early versions of Windows 10 it was not readily possible to downgrade from Windows 10 Enterprise to Win 10 Pro.  In fact, the supported process was to perform a clean install.  The dance around that was to make some registry changes and then perform an in place upgrade using a Windows 10 Pro key.

Fortunately that has changed and you can now easily change from Windows 10 Enterprise to Windows 10 Professional simply changing the product key:

1. Make sure you are using Windows 10 1607 or newer (almost certainly what everyone has that is reading this today)
2. Right click on the START button and select SYSTEM
3. Scroll down and click CHANGE PRODUCT KEY OR UPGRADE YOUR EDITION OF WINDOWS
4. Click CHANGE PRODUCT KEY
5. Enter the Windows 10 Professional Product key
   1. If your PC shipped with Windows 10 Pro but you do not have a product key sticker on the PC, that key is likely in the BIOS.
   2. You can easily access that product key using NeoSmart’s free utility OEMKEY which you can download from HERE.

That it.  You do not even have to reboot anymore.
