How to REVERT to another default search provider in IE9?
I can change the default search provider in IE9 (I can successfully put mine in).  What I CAN'T do as yet is successfully UNINSTALL it.  Just changing it in the registry (not the official way) causes IE9 to revert it (as designed).  However to do it the official way requires getting a service ID from IOpenService and I can't seem to find one for the existing default (this is on a clean install (well, reset to defaults) of IE9 on Windows 7).

I don't have the proper ID for the old one.  I do have the GUID, but I've been unsuccessful finding an ID from it, and likewise to install a new ID, forgetting for the moment the potential for duplication, means having or creating an XML file and supplying that, and I just want to switch it back.

Any ideas?

Thanks
