XP: Tasklist.exe – Get a List of Processes From the Command Line

Tasklist.exe is the XP replacement for tlist. From a command prompt it allows you to get a list of active processes from the command line.

Tasklist.exe allows a user to get a running list of tasks/processes on their system. Often this is a nice tool to use if a virus or spyware is keeping you from opening the task manager by CTRL-ALT-DEL.

Update: An alternative method using the Windows Instrumentation command-line interface (WMIC) is also available.

Users of XP home do not have this file by default. You may download it from one of these two sites:

Place it in your c:\windows\system32 folder.

Running tasklist:

    1. Click Start
    2. Click Run
    3. Enter cmd.exe in the textbox and click OK
    4. Type tasklist with additional arguments in the command window

Common uses and output are…

Image Name PID Session Name Session# Mem Usage
================ ======== ============
System Idle Process 0 Console 0 16 K
System 4 Console 0 44 K
smss.exe 660 Console 0 48 K
csrss.exe 724 Console 0 1,352 K
winlogon.exe 748 Console 0 2,132 K
services.exe 792 Console 0 2,096 K
lsass.exe 804 Console 0 1,436 K
svchost.exe 972 Console 0 1,700 K
svchost.exe 1040 Console 0 1,328 K
svchost.exe 1136 Console 0 14,068 K
winampa.exe 1664 Console 0 288 K

Say I wanted to kill winampa.exe. It’s easy… from your command line just type tskill winampa and all your active winampa tasks will be killed. You can see how this would be helpful in killing nasty spyware that prevents you from opening the task manager. Other sample inputs and the help file in included below.

tasklist /m shows the associated active dll files as well.
