How can you enable an ActiveX plugin via the registry? (IE8, Windows 7)

Question

At our enterprise we have an ActiveX plugin in IE that is currently disabled for at least some of the users. I need to enable it for everyone, and I'm not sure but I think there's a way to toggle the disabled/enabled status for a plugin via the registry.

Anyone know how to do this?

Solution

If you can push a script that will write your CLSID to:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Ext\PreApproved

...that should enable it. For more details on ActiveX security wrt instantiation, see this document.

And don't forget to implement IObjectSafety.
