Sometimes we use Taskmgr to kill some stubborn processes, don't be bundled! It's easy to get it. Look at the following: c: /> ntsd -cq -p pid This is the Win2000 itself, the specific method is: start Menu -> C: / NTSD -CQ -P PID, press Enter, huh, kill kill! What is PID? You can use Ctrl Alt Del this key key? The PID project in the list is what we need, In addition to the system necessary, this order can be killed in the process, and there is no way .... only system, smss.exe and csrss.exe can't 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.
