When you add a new desktop shortcut to the desktop - it allocates a standard explorer icon. I have changed these to more descriptive icons stored on my hard disc by right clicking the icon, selecting change icon, browsing to my file of icons (.ico files)clicking apply etc. The chosen icon then appears on the desktop.
However - sometimes, for no apparent reason, certain icons randomly revert to the explorer icon. After a reboot - the icons may - or may not - correct themselves.
If I right click on the faulty ones the heading of the web document tab still shows the correct icon but I have to go through the procedure of changing the icon all over again to get the specific icon back on the desktop.
This used to happen from time to time when I used Windows XP - but seems more prevalent on Vista.
I have searched the Microsoft knowledge base in vain - does anyone have a solution...?
