How to Close the Process that Task Manager Can’t Close


What if you find some suspicious processes in the process list of the task manager and use the task manager to shut down the related processes but can’t shut them down? How to solve it? Next, this article will share with you the relevant solutions.

Windows XP/2000 Task Manager is a very useful tool, which can let you see which programs (processes) are running in the system. As long as you look at the process list in the Task Manager at ordinary times and are familiar with the basic process of the system, you can find suspicious processes at any time, which is of great benefit to prevent Trojans and viruses!

1. Which system processes can’t be turned off

When Windows runs, it starts multiple processes. As long as you press the “Ctrl + Alt + Del” key to open the task manager, click the “View” / Select column, check “PIO” (Process Identifier). Then click the “Process” tab, you can see these processes.

However, there are some processes that individual users do not need at all, such as Systray.exe (display system tray horn icon), Ctfmon.exe (Microsoft Office input method), Winampa.exe, etc., we can completely prohibit them, which will not affect the normal operation of the system.

2. How to close the process that the task manager can’t shut down

If you can’t shut down a suspicious process in the task manager, you can use the following method to force the shutdown. Be careful not to kill the system core process in the process table:

1. Use Windows XP/2000 tools

Since Windows 2000, Windows system has brought a user-mode debugging tool Ntsd, which can kill most processes, because the process attached by the debugger will exit with the debugger, so long as you use Ntsd to call out a process from the command line.

Then exit Ntsd to terminate the process, and use Ntsd will automatically get Debug privileges, so Ntsd can kill most of the processes.
Method of operation: Click the “Start” / Program / Accessories / Command Prompt, enter the command: NTSD – C Q – P PID (change the last PID to the PID of the process you want to terminate).

In the process list, you can find the PID of a process. For example, we need to close the Explorer.exe process in Figure 1. Enter ntsd-c Q-P 408. The above parameter-P means the process PID is followed by the parameter-p, and-c Q means to execute the debugging command to exit Ntsd. Pass the above parameters from the command line.

2. Use special software to kill processes

Task Manager can’t kill the process, you can use special software to shut down. There are many software that can kill processes, such as process killer, IceSWord, Willowleaf Eye Wicker, System View Master, Kill Process, etc.

Process Killer 2.5 is downloaded as follows:
Download address:

It can browse all the processes running in the system, including those that cannot be seen with Ctrl+Alt+Del. It can simplify the process and automatically stop all the processes except the basic process of the system. It can clear Trojan horse and virus process to some extent. You can use it to stop any running process at any time and select the process. Press the “Stop Process” button.
