The desktop is the main Windows window that the user interacts with. It displays the objects and management tools of the operating system. The explorer.exe process controls the loading of the Desktop.
Sometimes, as a result of a virus infection or registry failure, the process does not work correctly. In this case, the "Desktop" and the "Start" button may not load. To get your system back to normal, you must first get rid of the viruses. Run a reliable antivirus program (such as DrWeb Curreit) in deep scan mode on your computer.
Problems can be caused by a virus corrupted explorer.exe file or removed by an antivirus program from the Windows root directory. Find this file in the installation disk or on another computer and copy it to the C: / Windows folder.

In the "File" menu, select the "Database update" command and write the program along with the updated databases, for example, to a USB flash drive. On the affected computer, use the Ctrl + Shift + Esc or Ctrl + Alt + Delete combination to call the "Task Manager". Click the "New Task" and "Browse" buttons to launch AVZ4.
Choose the "System Restore" option from the "File" menu and check the boxes for "Desktop Restore", "Remove Debuggers" and "Startup Key Restore". Click the "Perform Operations" button. When the system prompts you to reboot, answer “Yes”.
If you cannot invoke Task Manager, restart your computer and log on in Directory Service Restore mode. To do this, after a single beep POST, press F8 and select the appropriate option in the boot menu.
Call Task Manager again. Click New Task and type regedit. In the Registry Editor window, find the HKCU / Software / Microsoft / Windows / CurrentVersion / Policies key and right-click on it. Select the "Permissions" option, then check your account and check the box next to "Full Control". Reboot to normal mode.
