Have you ended a task manager and then gotten 30 seconds of countdown before it restarts or shutdowns by itself? Lets say you are trying to end a task of a running virus from your windows task manager."this system is shutting down.please save all your work in progress and log off. Any unsaved changes will be lost..."
To be able to kill the process without getting your system shut down, use the "END PROCESS" from windows Task Manager instead of end process.However, if you're trying to kill a virus process, chances are that it has already disabled your Task manager. When trying to launch Task manager, you get the error "Task manager has been disabled by your administrator".
Instead of trying to restore Task manager from registry, you can download a very useful tool called Process Explorer by Sysinternals(live.sysinternals.com) to do it. Simply right click on the process, and select " Kill Process Tree".
Alternatively, you can use the keyboard shortcut "Shift+Del". No more getting " This system is shutting down" error when trying to kill a virus process.
