Personally, I managed to delete Show Desktop, from Quick Launch and it was a bit stressful, because I was used to using “show desktop” , when I had many open windows.
icon “Show Desktop” , is not a regular program of shortcuts. To restore this icon “show desktop” (display work space), in the bar of Quick Launch , we need to follow a few steps.
1. Click Start , click Run, write notepad, and then click OK.
2. In Notepad, write the following text below, on lines (or copy/paste, below):
[Shell] 
Command=2 
IconFile=explorer.exe,3 
[Taskbar] 
Command=ToggleDesktop3. in the menu File, din Notepad , click Save As and save the file on the desktop with the name Show Desktop.scf .
*The notpad can automatically add the .txt extension, this file. Delete the .txt extension and add the .SCF extension . If you saved the file under the .txt extension, you can change with “rename” . Delete the name Show Desktop.txt and instead of writing Show Desktop.scf. A Windows of Averisment will be opened to ask you if you agree with changing the file extension.

Click “Yes“
After being saved on the desktop file Show Desktop.scf , it will have to be taken to the Quick Launch bar. The simplest method is to take it with the mouse. Select and pull (Drag & Drop) the file on the desktop, above the quick launch bar.

In this way , Create a shortcut of the Desktop.SCF show in Quick Launch. If you want this order file to be added directly to Quick Launch, copy the file to the folder:
C:Documents and SettingsUsernameApplication DataMicrosoftInternet ExplorerQuick Launch
*Username , represents the name of the authentication account on the operating system.
The method is valid for operating systems Microsoft Windows NT, Microsoft Windows 2000, Microsoft Windows XP and Microsoft Windows Vista .
