I'm looking to push out en mass the following:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Driver Signing]

However, neither ZEN nor a double-click on the .REG file itself modifies the registry. Is My Computer, Properties, Hardware, Driver Signing the only way to change driver signing policy?

TIA, Brian
