The Windows Task Manager is a powerful Windows tool. It displays information about the processes running on your computer and the resources being utilized. It gives Windows users the ability to monitor, manage, and troubleshoot apps and tasks.
How to kill some tasks
Press the keys Ctrl+Shift+Esc simultaneously or open the Run windows (Windows+R), and type taskmgr.
Windows Task Manager
To force a frozen/unresponsive task/app to quit, select the task you want to kill, and then smash the End task button.
You can also force quit an app from the Command Prompt. Launch the Command Prompt by opening the Run windows (Windows+R) and typing cmd. Then, type tasklist. It displays a list of currently running processes. Processes are programs in execution, i.e., running on your computer. To force quit a frozen program, execute this command: taskkill /im program.exe, e.g., taskkill /im msedge.exe, taskkill /im chrome.exe, or taskkill /im vlc.exe
The Task Manager’s Processes tab shows a list of processes (apps, background processes, and Windows processes) running on your computer. The Task Manager’s Performance tab shows real-time graphs displaying the usage of system resources. These include the CPU, Memory, and GPU.
The Task Manager’s Startup tab lists all the applications that Windows automatically starts when you log into your system. To disable one of these applications (e.g., Zoom, Microsoft Team, Microsoft OneDrive, Google Chrome, Skype), right-click on it and select Disable.
The Task Manager’s User tab displays all the users that are currently logged in and their running processes, so you are able to right-click another user to force them to sign out. The Task Manager’s Service tab shows a list of the system services or background tasks running on your system.
If the Task Manager application is not good or powerful enough for you, you can use Process Explorer. This is a free lightweight program that is part of the Sysinternal suite from Microsoft. Sysinternals are utilities to help you manage, troubleshoot and diagnose your Windows systems and applications.
Process Explorer
To view all active processes, open Activity Monitor from your Applications folder. There are five tabs across the top of its window: CPU, Memory, Energy, Disk, and Network. It lists all active processes according to the percentage of the resource (CPU, Memory, and so on) they are using.
To kill a problematic process, click on the process and then on the X in the top left of the Activity Monitor toolbar.
Activity Monitor
Besides, you can clic the Apple , then select Force Quit…, select the application and smash the Force Quit button.
Do you want to kill a problematic process from the terminal? Type kill -9 followed by the process’ PID number. How do you know the PID number? Type ps -ax | more or top and it will display and update a sorted list of currently running processes in your system. For each process, you’ll notice a PID number in the list. This is the PID (process ID), i.e., it uniquely identifies the program or process running on your system.
To easily remove startup items, go to System Preferences, Users & Groups, click the lock and type in your password. Next, select your username in the left panel and click the Login item tab. Select all the applications that you no longer use, and finally click the - button.
You can kill processes by name using killall, e.g., killall gimp. What should you do when your Linux desktop freezes or a program stops working? 1. Open a terminal: Ctrl + Alt + T(Gnome)/Mod + D (i3). 2. Type xkill, hover your cursor (it should have turned into an X) over the program and do a left-click to kill it. 3. If that does not work, type Ctrl+Alt+F1 to access a terminal that is not bound to the current graphical session, kill the problematic application (killall) or reboot (sudo reboot).
Conky is a system monitoring program for Linux. Let’s configure it by editing its configuration file, nvim .config/conky/conky.conf
