" I increase the icon cache, On XP the Max Cached Icons is set too low,
to changed this got to regedit,HKEY_LOCAL_
MACHINE-Software-Microsoft-Windows-currentversion-Explorer
in the right window, double click max cached icons, type the value 8192 ,then reboot you should see a big speed boost icon load, and opening folders.
I opened up the regedit and that key string isnt even there...why is that?
