Reset the Active-X Information Bar

I was doing some Active-X control testing where an Active-X control was not loaded and the Information Bar is displayed.

In one test I allowed the control to be run. I needed to undo that choice but couldn't figure out how. On Windows Vista with IE the solution was in the registry under:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Ext\Stats

The specific Active-X control is specified by CLSID. So in my case it the Windows Media Player Active-X CLSID is 22d6f312-b0f6-11d0-94ab-0080c74c7e95.

Removing the subkey that specifies the domain caused the information bar to appear on reload. In the example below I removed iexplore\AllowedDomains\ringrevenue.com

For Windows XP & IE 7 you will only see the key "iexplore" (no subkeys). Delete the iexplore key.
