Hi Jessie,

You might try doing a restore point to an earlier date and see if that works.  Window Blinds would not change your default program icons.  Another thing you could try is cleaning out the icon cache on your computer.  You can find instructions for that in How To Geek.  However, if you are not comfortable with editing the registry, it would be better to try using a restore point to a date before the icons changed.  If you mess up the registry, you could have much bigger problems. 

If you are talking about the Start Menu, that is determined by the skin as is the Start Button but I've never had WB change the actual program shortcut icons in the taskbar.  You could also simply try creating new shortcuts for the affected programs if using restore doesn't work.
