Action of Refresh in WinXP Home   

I have some special icons assigned to my Desktop 
folders for easier visual identification.  For 
whatever reason some of them change back to the plain 
ole Window's folder icon and I have to change back via 
Properties/Customize.  Afterwards I'll click on 
REFRESH and the screen blinks.  Does this really do 
anything towards refreshing a link somewhere in the 
bowels of WinXP system?
Thanks,
Don
