XP: kill a Windows process from the command line with taskkill

The ability to perform tasks from a system’s command line allows those tasks to be used in batch files. This recipe describes several uses of taskkill to terminate Windows processes.

If you know the name of a process to kill, for example notepad.exe, use the following command from a command prompt to end it:

taskkill /IM notepad.exe

This will cause the program to terminate gracefully, asking for confirmation if there are unsaved changes. To forcefully kill the same process, add the /F option to the command line. Be careful with the /F option as it will terminate all matching processes without confirmation.

To kill a single instance of a process, specify its process id (PID). For example, if the desired process has a PID of 827, use the following command to kill it:

taskkill /PID 827

Using filters, a variety of different patterns can be used to specify the processes to kill. For example, the following filter syntax will forcefully kill all processes owned by the user Quinn:

taskkill /F /FI "USERNAME eq Quinn"

The following table shows the available filters and their use.

Filter Name Valid Operators Valid Value(s)
----------- --------------- --------------
IMAGENAME eq ne Image name
PID eq ne gt lt ge le PID value
SESSION eq ne gt lt ge le Session number.
CPUTIME eq ne gt lt ge le CPU time in the format
of hh:mm:ss.
MEMUSAGE eq ne gt lt ge le Memory usage in KB
USERNAME eq ne User name in [domain\]user
MODULES eq ne DLL name
SERVICES eq ne Service name
WINDOWTITLE eq ne Window title

eq: equals ne: not equal
gt: greater than lt: less than
gt: greater than or equal le: less than or equal

    Check for hardware or memory faults. If there are hardware issues then it will slowly corrupt your OS in odd ways eventually causing it to crash more often.

    Also check for driver issues/conflicts. If a device keeps making hardware interrupt calls it will force the system to respond but if the driver is not going to respond properly it may freeze or just take forever to come back.

    anyone know which service is associated with this? I get the following reply when I run this from the cmd line:

    “ERROR: The service cannot be started, either because it is disabled or because it has no enabled devices associated with it.”

      Taskkill uses WMI API to search process by name. Enable Windows Management Instrumentation (winmgmt) to use /IM.

    “gt: greater than or equal le: less than or equal”

    This is incorrect. “ge” is greater than or equal.

    @thedylman These utilities are available only for xp pro.
    You can couple it with the tasklist /SVC command to see the process id of the process and then use taskkill on it that way you can be sure of the process you are terminating and can also spot malwares. See this link

    I guess you learn new things every day. I’ve been using the command line for years, and I didn’t know about this. I’ve always been using tskill, though I suppose there is little difference in the end, eh?

    It simply does not work [if anyone says 'yes, it works' then simply lies].
    You run it, it says ‘SUCCESS: The process “xxxxx.exe” with PID 1860 has been terminated’ but… process still running. You run second time and again ‘success’ ‘SUCCESS: The process “xxxx.exe” with PID 1860 has been terminated’… and so on.

    It’s amazing to know that XP has such built-in command.
    I’ve tried to use Toolhelp32 API to kill processes, but it doesn’t enumerate processes spawned by another users (not current).
    That tool kills processes with image name independent of the user’s context it’s running!

    Ok, but what about processes that don’t terminate in XP although you called the taskkill /f /im PROCESSNAME ??!?!?!? Some process might say : “Access denied” . How are those killed ?! And please don’t tell me it doesn’t work – The shutdown kills everything, wether or not it is “access denied”, so how does the shutdown get it right to kill ALL processes ?!

    Don’t know if it is an issue for all Windows, but i found on a windows 2003 server that the operator “gt” fails on my filter upon CPUTIME. (While this works correctly for tasklist.exe) my workaround was to use “ge” instead.
    tasklist /FI “CPUTIME gt 00:30:00″ => success
    taskkil /FI “CPUTIME gt 00:30:00″ => fails (no match found)
    taskkill /FI “CPUTIME ge 00:30:00″ => success


    • January 07, 2011 at 3:57 pm, Fredgimz said:

      Well, finally this was just a lucky strike, i cannot reproduce this..
      The problem seems to concern the time string, results are very very inconsistent, with any combination of gt ge lt le.
      It even doesn’t recognize my filter if i use 00:00:51 so 51s or above, while “51:51:50″ and even “00:69:00″ are fine !!!
      It looks like the getting of time or something is completely fucked up…

      Yea, that on gt in the filters is a typo. It should be ge.

    I dont understand, because I check the services options between both operating systems and change them to be the same.

When this happens, I can’t access task manager as usual (it just opens to a blank box) but, in order to log off or restart, I need to kill a certain process related to the adapter for dual monitors. Until now, I had to depend on calling someone in the office to shut off and turn on the PC for me. Obviously, that only works during business hours! Appreciate the help.
