Downgrade Windows 10 Enterprise to Professional Failed

Question

I did the process of downgrading Windows 10 Enterprise to Windows 10 Professional without reinstalling by just activating Windows 10 using Pro license key but it failed for several versions such as 1809, 1909 and 20H2 while version 1607 was successful, the question is why for versions above 1607 it failed?

Answer 1

Hello,

You need to use Pro edition generic key first, then you can downgrade to Pro edition:

After that, you can activate Pro edition with your original license key.

Hope this helps!

Answer 2

From your Windows 10 running Version 1511 and higher version, enter the Windows 10 Pro Default key under change product key.

This default key will not activate the system, just take you to Pro so you can activate using a valid Pro key that you will provide. Since you have ever used activated Enterprise edition, you don’t need to buy a Pro key for activation, make sure computer is Internet connection, system will activate itself automatically.
