Small tip - if you updated your Windows and you now have the really annoying "Windows search" come up as the search window instead of the good old "Search companion", do this to restore it back and get rid of "Windows search".
Open registry (Start -> Run -> write "regedit") and find this key:
HKEY_CURRENT_USER\Software\Microsoft\Windows Desktop Search\DS\ShowStartSearchBand
Change the dword-value from 1 to 0 , and it will change the search back to "Search companion".
P.S. Tested on XP, I don't know if it works on Vista or not.
