Icon Fix
I have windows 8.2 I found the above listed guides didn't work. I don't have 16 bit mode, nor do I have the iconcache.db. Here's what I did
1. Right click the broken icon
2. Select properties
3. Select Change Icon at the bottom of the options in the shortcut tab
4. Select the default icon from the pop up
5. Click OK
6. Click Apply
Cheers.
