Q: How can I turn off a process that cannot be related to the task manager? I found a process in my machine for some time. As long as it is turned on, I can't pay attention to the task manager, I can't pay attention 1: Killing the process is easy, just find a tool. For example, ICESWORD. The key is to find the startup method of this process, otherwise the next restart it is coming again. By the way, you will teach everyone. In fact, it can kill most processes with Windows: C: /> NTSD-C Q -P PID only System, Smss.exe and CSRSS.exe cannot kill. The first two is pure core, and finally the Win32 subsystem, the NTSD itself needs it. NTSD starts from 2000 is the user status debug tool with the system. The process of being attached to the debugger (Attach) is exited with the adjustment, so it can be used to terminate the process on the command line. Automatically get DEBUG permissions using NTSD, which can kill most of the process. NTSD will open a debug window, which is originally uncontrolled under the pure command line, but if it is just a simple command, such as exiting (Q), pass the command line from the command line with the -c parameter. NTSDNTSD also provides software developers in accordance with the practice. Only the system developers use this command. For more information, see the help files attached in NTSD. Usage: Open a cmd.exe window, enter: NTSD-C Q -P PID put the last PID, change the ID you want to terminate. If you don't know the ID, Task Manager -> Process tab -> View-> Select Column -> Hook "PID (Process Identifier)", then you can see it. Answer 2: There are two good stuffs Tasklist and TSKILL under XP. Tasklist can list all processes and corresponding information. Tskill can kill the process, the syntax is simple: TSKILL program name! !
