The XP/Vista program tasklist runs from a command prompt and shows the programs currently running with a number of options. The ability to run commands from the command prompt allows automation with batch files. It is also often quicker to type a simple command to get specific output than to mouse through a series of menus.

This shows each program running on one line and includes the PID (process ID) number, the memory usage, as well as the image (application) name.
Running taskkill with the verbose flag shows additional information including the user running the application, CPU execution time, and the title of the window:
The tasklist command permits the use of numerous filters to view only certain applications. For example, to list only applications run by the user Quinn, use:
tasklist /FI "USERNAME eq Quinn"
Or, to list all applications currently running that have linked the DLL msvcrt.dll, use:
tasklist /FI "MODULES eq msvcrt.dll"
The following table shows the available filters and their use.
