Found some possible workaround:
here is a “simple” hack which allows you to embed the downgrade procedure in Windows 7.
Click Start.
In the Search Box, type regedit and press Enter.
Navigate to this registry key: HKEY_LOCAL_MACHINESoftware Microsoft Windows NTCurrentVersion
In the right pane, click EditionID and ProductName and give them the value which corresponds to a lower Windows 7 edition. Here is an example:
Windows 7 Home Premium (downgrade from Windows 7 Ultimate to Windows 7 Home Premium)
EditionID: HomePremium
ProductName: Windows 7 HomePremium
Start your Windows 7 installation by inserting your Windows 7 Disc.
Now, Select Upgrade as type of installation. Follow the instruction on the screen.
Reactivate your operating system.”

If modifying the registry is scary try this application to change it for u:
