Desktop [icon missing from Quicklaunch bar]

I had an Icon on my task bar that read "Show Desktop ". When I clicked on the Icon I would be switched from open Windows to the desktop where I can choose from my shortcut Icons. Some how the Icon has been deleted from my task bar and now I have to click on a shortcut to the Windows Explorer to look at a list of items on my desktop. I don't want to use Windows Explorer to view the list of items on my desktop. I want to replace the "Show Desktop" icon on the taskbar but now I can't find the icon. Do you know where I can find the missing Taskbar Icon? Thanks for your help.

 

1. Click Start , click Run, type notepad, and then click OK.
2. In Notepad, type the following text on individual lines:
[Shell] Command=2 IconFile=explorer.exe,3
[Taskbar] Command=ToggleDesktop
3. Click File, click Save As, and then save the file to your desktop as Show Desktop.scf.

Then just move the file to your quick launch bar.
