Windows 7: Where are IE9 settings stored on your PC?

More specifically I'm talking about the Search Provider information.
You can add them from the Internet Explorer Gallery website.
In this website you select which specific search provider you want to add, and then there's a javascript call that gets some info from a specific xml file and incorporates them "somewhere" in your PC.

I don't know the details of how this happens, I can imagine two scenarios:
1) The XML file gets copied in your HDD somewhere, one xml for each search provider
2) The info inside the XML gets copied in a single setting file somewhere in your PC




I can provide more examples and pictures if you want me to. I need to manually fix an error in one of these URLs, and to do so I need to find where this kind of info is stored.


Thanks for your support


P.S.
Wherever they are, I strongly suppose that they're in a common place and not specific for the application, because I noticed they are "shared" between IE9 32bit and IE9 64bit. So this must mean Windows stores setting for both in the same place.
I might be wrong of course, it's just a supposition.

I believe they're in the registry under HKCU\Software\Microsoft\Internet Explorer\SearchScopes. Each provider is in a sub-key with a GUID name.

And here's why I couldn't find them!

OMG you're fantastic!
How can I thank you? What can I do for you? Thank you so very much! I manage to fix this silly mistakes


In case anybody was curious allow me to explain what is it I had to fix.
You'll see some italian stuff in the links, pardon me about that, I'm sure you'll all grasp the overall meaning of things.


Basically I installed Windows 7 x64 Pro OEM on a new PC I just bought. Once I was done, after a few days, I noticed an odd behaviour from IE9. Know the function that allows you to search, with the default search provider, in the address bar?
Even if I had installed Google Italy, whenever I put something to search for, the result was that I was brought to the homepage of google, instead than on the results page. It was a very strange behaviour, and even more because I afterwise noticed this happened ONLY if I was logged unto my Google account.
Since everything was working perfectly on my old PC, next thing I checked is for the settings of Google Italy in my old PC, and noticed there were some differences! I wasn't surprised of course.
Check the pics, first one is the new PC, second one is the old PC.

After a few more tests I understood that the Google Italy I installed on my old PC was an old "addon", Microsoft had replaced it with a new one (the one on my new PC), I don't know exactely when, and the search url of this new "addon" had a small syntax error.
Compared the two:

Old addon syntax: http://www.google.com/search?hl=it&q={searchTerms}&meta=
New addon syntax: http://www.google.it/#hl=it&source=hp&q={searchTerms}&aq=f&aqi=g10&aql=&oq=&gs_rfai=&fp=9fca69c98b5d77d7

Then I did some more researchs on the IE9 addon website, www.iegallery.com
I went to the page of the Google Italy addon and from there I understood how it works.
Basically it's a simple javascript call that gets data from an XML (in the example above from THIS xml) and noticed THAT's where the error was hiding!
I thought if I could manage to find WHERE on my PC that string was goin to get stored, I could have easily modified it myself and changed it with the working one.
And that's exactely what I did



So once again, thank you so very much for helping me!!! I owe you one man
