SYMPTOMS
If you press CTRL+ALT+DELETE immediately after you initiate a shutdown from the console on a Windows NT-based computer, the shutdown may be halted, leaving a blank desktop on the screen. Pressing CTRL+ALT+DELETE again opens the Windows NT Security dialog box.



CAUSE
There is a small time window during the shutdown process during which you can halt shutdown by pressing CTRL+ALT+DELETE. However, this occurs only after all of the currently logged-on user's processes have been stopped, but before the user is logged out. This is why a blank desktop is displayed. You can reinstate the user environment by starting Explorer.exe from Task Manager.
