This is not somthing I usually need to do but I collect this kind of information because it comes in handy at times.

1. Launch the Registry Editor (Regedit.exe).
2. Go to HKEY_CURRENT_USER\ SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer.
3. Right-click the Explorer subkey and select New DWORD Value.
4. Name the key NoClose and press Enter twice.
5. Type 1 in the Value Data text box and click OK.


To enable the setting, close the Registry Editor and restart your system. Once your system restarts, you will not be able to it shut down by clicking the Shutdown button on the Start menu. This will prevent most users from inadvertently shutting down the computer.

When you do want to shut down your system, just access Task Manager by pressing Ctrl + Alt + Delete, then pull down the Shut Down menu and select the Turn Off command.
