how to disable Welcome to the 2007 Microsoft Office splashscreen when opening Microsoft picture manager

it can be disabled by setting the following registrykey

HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Common\General\ShownOptIn"=dword:00000001

I have been converting the adm file to a admx file, to be able to disable the welcome splashscreen  via gpo

ADMX file: Office2007DisableSplashScreen
