Microsoft's little known invincible command

                  Q: How can I turn off a process that can't be closed with Task Manager? I found out that there was a process in my machine some time ago, as long as it was turned on, I couldn't turn it off with the task manager.

A 1: kill the process very easy, just find the tool will do. Such as IceSword. The key is to find the way to start this process, or it will come out next time you restart it. By the way, I will teach you a trick. Its practical Windows built-in tools can kill most of the process:

c:\\>ntsd -c q -p PID

Only System, SMSS.EXE and CSRSS.EXE can not kill. The first two are purely kernel-mode, and the last one is the Win32 subsystem, which is required by ntsd itself. Since 2000, ntsd is the user-mode debugging tool that comes with the system. The process attached by the debugger exits with the debugger, so it can be used to terminate the process at the command line. Using ntsd automatically gets debug permissions, which can kill most of the process. Ntsd will open a new debug window, which could not be controlled under the pure command line, but if it is just a simple command, such as exiting (q), it can be passed from the command line with the -c parameter. NtsdNtsd is also provided to software developers by convention. Only system developers use this command. For more information, see the help file included with NTSD. Usage: Open a cmd.exe window and type:

ntsd -c q -p PID

Change the last PID to the ID of the process you want to terminate. If you don't know the ID of the process, Task Manager - Process tab -> View -> Select Column -> Check "PID (Process Identifier)" and you will see it.

Answer 2: There are two good stuff xp tasklist and tskill. The tasklist can list all processes, and the corresponding information. Tskill can kill the process, the syntax is very simple: tskill program name! !
