Unable to click desktop (a funny trick)

Allright, this one is really old but sometimes users will not know what happened. Just make a screenshot of your desktop by pressing "Print Screen" on your keyboard (sometimes shown as "Print Scrn"). Now go to Paint andPaste(Ctrl+V). You should now have an image of your desktop. Save the image to your PC (not on your desktop) and save it as BMP. You'll now have the file like this:C:/Desktop.bmp. Next, right-click on your desktop and selectProperties. Select the tabDesktopand clickBrowse...Navigate to your screenshot and pressOKto set it as your background you are almost done now right click your destop again to navigate to arrange icons by aundunchek show destop icon there you have it the icon now the destop icon cannot be clicked
