How can I remove items from the "Look in:" combo box in Visual Studio's "Find and Replace" dialog?

These entries are located in the following registry key:

HKCU\Software\Microsoft\VisualStudio\10.0\Find

They will be prefixed with Query and then followed by a number.

The location for those entries is:

HKEY_USERS \ {user guid} \Software\Microsoft\VisualStudio\10.0\Find

where [user guid] is the guid for the current user.

really I just searched the registry for some entries that I added by accident while testing if there was another way to remove them.
