Often Explorer issues, (your Desktop is just an Explorer), can be traced back to bad Internet Explorer Add-ons, so if you are willing to lose all your IE Favorites, Login details, Cookies, and so on, you can remove all the IE Add-ons by opening IE, goto Tools > Internet Options, then the Advanced tab, and hit the Reset button.
If you do not wish to lose all that other information you can try disabling Add-ons to eliminate any bad ones.
