While many of us use Windows Explorer on a regular basis to view and make changes to our systems, many of us never use the "My Computer" desktop icon. For those of us who like desktop shortcuts, why not make the "My Computer" icon launch Explorer when double-clicked?
A quick RegEdit makes short work of this problem. Remember, RegEdits can harm your system if you don't perform them correctly, so be sure to back up your data first!

You're all set. When you double-click "My Computer," you'll launch Windows Explorer. Happy day!
