If you are interested in Windows registry manipulation it would be worth chasing the thread in their archive.

I'm trying to copy a value from HKLM to HKCU for application rollout via bulk installation by an administrator but individual Windows user authentication. The installer can write to HKLM but the user needs to see the value in HKCUAny hints appreciated. Thanks Mike Getting this ...
