Icons on the destop will slow down the booting speed of windows to avoid this, we have to increase cache memory of the icons.
iconcache.db is the file managing the icon cache..
follow this steps to do that
start =>run in that type regedit
in regedit window HKEY-LOCAL-MACHINE =>SOFTWARE=>M*cro$oft=>WINDOWS=>CURRENT VERSION=>EXPLORER=>MAX CACHED ICONS
in that 500 will be the existing value to edit that double click that, now u can see edit string on value section type 2000 instead of 500.
close regedit and now reboot windows now u can see the difference..
