Windows Task Manager is definitely not one of the best things to manage tasks and processes on your computer, it lacks a lot of features which we desire to have a better control over running applications and processes.
In the past we had discussed about Process Explorer, a software utility that allowed you to manage tasks efficiently, along with the ability to suspend memory and CPU hogging tasks instead of terminating them forcefully.
Kill Process is another Freeware software utility, that will allow you to kill tasks just like a the task manager.
To kill any running tasks or processes, simply click on the task and click on the Terminal button to kill the process. You can also terminate multiple running processes with a single click along with the ability to kill running services, which are different from processes, since they run in the background.
