Windows 7 Taskbar Icons Not Displaying Properly After Repair

If some of your icons display like empty boxes after a repair to the system because of some reset, then follow these instructions. They worked for me.

1. Open the task manager in the processes tab.
2. Kill explorer.exe.
3. From the File menu in the task manager, choose New task (run...)
4. Execute the following:  
1. cmd /c del %userprofile%\AppData\Local\IconCache.db /a
5. And restart explorer running: 
1. explorer.exe

Everything should be fine now!
Tested on Windows 7
