Have you ever had a program freeze and refuse to close or disappear? A very annoying problem is when a poorly written application crashes and refuses to close. Or maybe you’ve noticed that your computer is suddenly running very slowly, but there’s no clear indication as to why? In that case, you may have a process on your system that’s hogging all the CPU time or taking up a lot of memory.

Well, the Windows Task Manager can help you in some of these situations to determine the cause and end the problem application. First, the purpose of the Task Manager is to provide information about your computer's performance, along with details about currently running programs, processes, and services. It also provides the ability to monitor your network traffic if you are connected to a network.

Let’s start by getting to know this very useful tool in Windows 10. You can reach Task Manager in a couple of ways:

1. Press Ctrl + Shift + ESC while holding down each key. Just like you would do Ctrl + Alt + Delete, which most people have done by now.
