Found 2 license keys in Registry
Recently I performed a clean install of Windows 10 Pro, version 20H2. I used the Media Creation Tool to do so and ended up with Windows 10 Home. Eventually I was able to get Windows 10 Pro installed and everything is working.
The thing I noticed was that both versions of Windows activated with no problem. In the past when I did this the Media Creation Tool installed the Windows edition that was previously installed on other computers.
I started doing web searches to find out where the license were stored on the computer and one search pointed me to looking in the registry. Under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\, I found entries for a DefaultProductKey and a DefaultProductKey2. The first has the information for Windows 10 Home and the other is for Windows 10 Pro.
Before I do anything rash, could this be why the Media Creation Tool behaves as it does? I seldom have a reason to have to do a reinstall and I currently have a USB drive that works, but if I needed to recreate new media it would help not to have to repeat this.
