Upgrading Windows 7 Home Premium to Professional
I have a HP machine that came with a free upgrade to Windows 7. I did a blank install for that upgrade. The version is Home Premium. I am wanting to use the virtural PC software from Microsoft, however it requires Professional version. Looking back I should just installed the MSDN version.I have a MSDN subscription, and use this machine for development. I am debating if I can just enter the key from the MSDN subscription for the professional upgrade. I don't want to re-install everything since I have all my programming software running good all ready. My goal is not to have to reinstall Adobe, VS 2008, SQL and etc softwareThanks for any help,David

You can perform an Windows Anytime Upgrade on your machine.This feature allows switching Windows editions without the need to reinstall.More information: http://windows.microsoft.com/en-us/windows7/products/windows-anytime-upgrade The following command on your Windows 7 Home Premium installation will list the Windows 7 to which you can upgrade:
dism.exe /online /get-targeteditions
The following command on your Windows 7 Home Premium installation will upgrade it to Windows 7 Professional:
dism.exe /online /set-edition:Professional /productkey:ABCDE-FGHIJ-KLMNO-PQRST-UVWXY

Hi all,
I'm sorry, this doesnt work for me. I am trying to upgrade from Windows 7 Home Premium to Windows 7 Professional.
I followed your instructions. Am I doing something wrong?
Here is what I tried, replacing the product key from MSDN with XXXX
C:\Windows\system32>dism.exe /online /set-edition:Professional /productkey:XXXXX...
Deployment Image Servicing and Management tool
Version: 6.1.7600.16385
Image Version: 6.1.7601.17514
Error: 50
Setting an Edition is not supported with online images.
The DISM log file can be found at C:\Windows\Logs\DISM\dism.log
I tried dism.exe /online /get-targeteditions and got the following response
C:\Windows\system32>dism.exe /online /get-targeteditions
Deployment Image Servicing and Management tool
Version: 6.1.7600.16385
Image Version: 6.1.7601.17514
Editions that can be upgraded to:
Error: 87
The Windows edition was not detected.
Verify that the specified image is a valid Windows operating system image.
The DISM log file can be found at C:\Windows\Logs\DISM\dism.log
Thanks much,
Guy
