Show you the desktop shortcut!

Method 1:
 
If you are too lazy to look down, you can remember the "win + d" shortcut key to quickly switch to the desktop. (The win key is located between Ctrl and Alt)
 
 
Method 2: (I used this method)
 
 
You can also click "Start> Run". In the displayed "run" dialog box, enter "REGSVR32/n/I: u shell32" (excluding double quotation marks. Note: there is a space after 32), and then press Enter. After a moment, the "DllInstall successful in shell32" prompt dialog box will pop up, so that the "show desktop" button will return perfectly.
 
 
Method 3:
 
You can create one by yourself.
Open notepad and enter the following content:
 
[Shell]
Command = 2
Iconfile1_assumer.exe, 3
[Taskbar]
Command = ToggleDesktop
 
 
The third line of code indicates the position of the icon. The number "3" indicates the position of the icon. When the number "3" is changed to "4", the icon is refreshed; when the number is changed to "6", the icon is changed to the recycle bin icon. Although the icon style has changed, it is also a "display desktop" function. Therefore, you can change the desktop icon. In fact, you only need to enter the path of your favorite icon after "IconFile =.
Click "file" --> "Save as", select "all files" in the file type, and add "display desktop. scf" (not including double quotation marks) to the file name.
Next, drag the saved file to the Quick Start bar. For future convenience, you can save the icon to the following path: C: \ Documents ents and Settings \ Administrator \ Application Data \ Microsoft \ Internet Explorer \ Quick Launch. Now, click "display desktop" to create a new job!
 
Method 4:
 
If you find this troublesome, there is another simple way to copy the "show desktop" shortcut from another computer. First, find the shortcut on another computer, press ctrl to drag the icon to the desktop, and then copy the "show desktop" to the storage disk or connect to the desired computer, upload the file and drag it to the Quick Start bar.
 
 
Method 5:
 
 
Or run "regedit" to open the registry and find the following key value: HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ System. In the window on the right, there is a DOWRD value: "NoDispCPL ", set the value to "0" or delete it.
