Hi guys,

I have about 30 x Win7 Enterprise machines we want to automate teh downgrade from Enterprise to Pro for, without nuking the data thats already there, so we can upgrade to Win 10 Pro.

I have found a registry hack to trick Windows 7 Pro to install over the top of Enterprise by overwriting a couple of registry keys with the details it verifies before installing.

reg add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion" /v EditionID /t REG_SZ /d "Professional" /f
reg add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion" /v ProductName /t REG_SZ /d "Windows 7 Professional" /f

But I am trying to find an unattended way to use the K2000 to do the Windows 7 Pro in-place upgrade so we don't have to do it manually.

A standard scripted install without any diskpart tasks etc doesn't work, it still seems to nuke all programs etc that were installed prior. I have seen this Win 10 upgrade post but I'm not able to modify it to work with a Windows 7 Pro install silently.

So i'm looking for any advice anyone might have?

Please and thanks. =)
