on windows 7 on IE9 I want to enable checkbox Enable Protected Mode using registry.

does anyone know what the registry keys are.

ive done a web search, found some things that werent really relative or if I applied them didnt work.

another question:
I think the sys admins may have applied the setting via GPO policy.
I think I may have to disable or bypass the GPO to apply the reg setting - anyone know how to do that?

pls see screen capture
many thanks
