End the lousy application

If the application that you are working on troubles you and doesn't quit even after injecting it with "CRTL+ALT+DEL" keys then you may likely end up with a big task of restarting your system to kill the running process. Instead you could follow these simple steps to put an end to the lousy process.

Open cmd prompt-via run and type cmd
Then type the command "TASKLIST" -this will list all the currently running processes in the system
Now, note down the process ID next to the process which you want to kill.
Then type, TASKKILL /PID (the process id).
If the process id is 2655 then type
taskkill /PID 2655
Sometimes you may have to force kill your application to end it so type the following
taskkill /F /PID 2655

That's it now it will solve your problems.
