The guide below will walk you through restoring the Windows desktop when it is not visible. Since the explorer process cannot be launched, the Windows desktop is not displayed when you login. This type of behavior is usually caused by malware or misconfigured programs that block the Explorer.exe process from executing.
When this happens, when you login to Windows instead of seeing the desktop, start menu, or your normal icons, you are shown a blank screen instead. When using Windows, under certain circumstances the Windows Desktop will not be shown.
