Ever mistype a path during Find and then have to live with it in the list forever?

Visual Studio stores those queries in the Windowsy Registry using the same basic pattern. For example, queries for Find are stored here:

HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\8.0\Find

You will find values named Query n where n indicates the order of the query in dialog. Simply delete or edit the value and you're done.
