There are some suspicious processes in the process List of Discovery Task Manager. You can't kill with Task Manager. Windows xp/2000 Task Manager is a useful tool to see which programs (processes) are running in the system, and to be familiar with the basic process of the system as long as you look at the list of processes in Task Manager , you can detect suspicious processes at any time, which is helpful to prevent Trojans and viruses.
One, which system processes can not be turned off
When Windows runs, multiple processes are started. Just press the "Ctrl+alt+del" key to open Task Manager, click "View"/select column, tick "PIO (process Identifier)", and click the "Process" tab to see these processes. However, there are some processes personal users do not use, such as Systray.exe (Display system tray small horn icon), Ctfmon.exe (Microsoft Office Input Method), Winampa.exe, etc., can be completely prohibited, this does not affect the normal operation of the system.
Second, how to close the Task manager can not kill the process
If you cannot close a suspicious process in Task Manager, you can use the following method to force the shutdown, and be careful not to kill the system core processes in the process table:
1. Using Windows xp/2000 with its own tools
Starting with Windows 2000, the Windows system comes with a user-state debugging tool NTSD that kills most processes because the process attached to the debugger exits with the debugger, so you can terminate the process by using NTSD at the command line and then exiting NTSD. and using NTSD automatically gets debug permissions, so NTSD can kill most of the process.
How to: Click Start/Program/attachment/Command prompt, enter command: NTSD-C q-p pid (change the last PID to the PID of the process to terminate). You can find the PID of a process in the process list, for example, to turn off the Explorer.exe process in Figure 1, enter: Ntsd-c q-p 408.
The above parameter-P indicates that the process PID followed, C-Q means to execute the debugging command to exit the NTSD, the above parameters from the command line passed the past on the line.
2. Use specialized software to kill the process
Task Manager cannot kill a process that can be closed with specialized software. There are many software that can kill processes, such as process killers, IceSword, Willow Wipes, System View masters, kill process, and so on.
