Since upgrading from Vista to Windows 7 the start menu is unable to learn what I look for when I type to search. It actually works for most items (and all newly installed programs for example). But some items like "Windows Update" just don't appear near the top no matter how often I have searched for them in the same way with exactly the same prefix.
I'd like to try to reset all learned data from the start menu. Where is it stored and how can I reset it?
