There are situations where the desktop background is visible and the mouse pointer works, but Explorer is dead and ctrl-alt-del and shift-ctrl-esc don't do anything, even though the keyboard is active and can be used to exit the screensaver. Remote Desktop is functional but doesn't help or provide any more functionality than at the host computer.
I believe this happens when Windows Update / Microsoft Update has initiated a reboot, but something is preventing the final shutdown. If the power button is configured for sleep or hibernate, there's apparently no way to recover from this; upon wake or return from hibernation, you end up right where you were. I usually end up just pulling the plug so on my next boot I'd be prompted whether to start Windows normally.
Will CTRL+SHIFT+ESC work when explorer.exe is not running? – firedfly – 2011-01-08T15:24:15.817
Definitely, yes. You can test this by manually killing the explorer.exe process from Task Manager itself. Close Task Manager... CTRL+SHIFT+ESC... voila. – Kez – 2011-01-08T15:25:35.547
Right click no the task bar and you will find the option : show task manager , follow kez's instruction after that – Shekhar – 2011-01-08T15:32:05.310
