FIXED - If rebuilding your icon cache does not fix your problem, maybe this will.
- Right-click on the blank page icon in your quick launch area and go to "Properties".
- On the "Short Cut" tab, select "Change Icon".
- Select the "Browse" button and browse to the executable of that program, probably in Programs. Example- Internet Explorer - browse to Program Files (x86), Internet Explorer, then click on iexplorer.exe and select open. A whole new set of icons to choose from will open.
- Select the icon you want. Click OK, then Apply.
The problem appears to be in the properties of your shortcut. "Target" and "Start in" may be blank or have a strange string as compared to the quick launch programs with icons that work - they point to their respective executables.
Hope this helps!
