Are you experiencing icon lag, while browsing thru all your Start icons and programs? Do you have a smaller menu delay and your icons need ages to load? No need to give up.
Just refresh the icon cache by deleting the IconCache.db file from your profile directory (usually /Documents and Settings/Username/Local Settings/Application Data). It will be automatically recreated.
Also this tweak will speed up the icons even more: http://www.tweakxp.com/tweakxp/display.asp?id=905
