The tasklist is the Windows command we use to list running processes on a Windows system. Often operates together with taskkill to terminate a running process or processes.

Open a command prompt (CMD or PowerShell), type tasklist, and press Enter:

tasklist

The following screenshot shows the default output of the tasklist command. It shows the Image Name (the name of the program that launched the process), process ID (PID), and the Memory Usage of each task.

The list can be long, so you may want to pipe the output to the more command (press Enter key to scroll through).

tasklist | more

If you want to end a process, use the taskkill command to terminate a running process using its process ID (PID) or image name.

taskkill /pid process-ID
taskkill /im image-name

For example, the following command terminates all instances of the notepad process by its image name.

taskkill /im notepad.exe

The Windows tasklist command supports three output formats: Table (the default), List, and CSV. To change the output format, use the /fo option, as shown in the following example:

tasklist /fo list

The following command saves the current task list into a text file in CSV format:

tasklist /fo csv > tasklist.txt

Running Tasklist Command on a Remote Computer

We can use the tasklist command to list running tasks on a remote computer. Use the /s and /u options to specify the IP Address and username of the remote computer, respectively.

tasklist /s 192.168.1.100 /u user1

However, the Firewall must be configured on the remote Windows system to allow the tasklist command. Click the link below for instructions on how to do it.

Command Options

The tasklist command has multiple options, which you can see by typing tasklist /?.

Examples

Use the /V option to display additional information, such as the program’s username and total CPU time:

tasklist /v

Show the list of dll files used by each process:

tasklist /m

Display the services provided by each process:

tasklist /svc

Using Filters to List Tasks That Match a Given Criteria

Using the /fi option, you can filter the command output to display the tasks that match the given criteria. The following section presents some examples.

List running processes:

tasklist /fi "status eq running"

List tasks that not responding:

tasklist /fi "status eq not responding"

List the process that has PID of 0:

tasklist /fi "pid eq 0"

List all processes owned by the user user1:

tasklist /fi "username eq user1"

Display the services are related the svchost process(es):

tasklist /svc /fi "imagename eq svchost.exe"

Show the processes using more than 10MB of memory:

tasklist /fi "memusage gt 10240"

You can get a list of all filters by running the tasklist /? command.

Using the Tasklist Command

The tasklist command is a powerful tool that allows you to view the processes running on your system.

Basic Syntax

To use this command, simply type:

tasklist

Upon executing this command, you will receive a list of currently active processes. The output includes several columns such as Image Name (the name of the executable), PID (Process ID), Session Name, Session#, and Mem Usage (memory usage).

Example Usage

When you run the command:

tasklist

You might see output like this:

Image Name                     PID     Session Name        Session#    Mem Usage
========================= ======== ================ =========== ============
explorer.exe                  1234    Console                    1       12,345 K
chrome.exe                    5678    Console                    1       45,678 K

In this example, you see explorer.exe and chrome.exe as running processes along with their associated PIDs.

Advanced Usage of Tasklist

Filtering Processes

The tasklist command can be enhanced with filters to refine your search based on certain criteria, such as status.

For example, to list only the running processes, you can use:

tasklist /fi "STATUS eq running"

This command filters the processes to display only those that are currently active, allowing you to manage them more effectively.

Exporting Process List

Another useful feature of the tasklist command is the ability to export the process list to a text file for later review or reporting.

To save the current process list to a file, you can execute:

tasklist > process_list.txt

The output file, process_list.txt, will then contain a complete list of currently running processes, making it easy to archive or analyze data later.

Other CMD Commands for Process Management

Using Get-Process in PowerShell

While CMD provides powerful commands for managing processes, PowerShell offers more flexibility and richer command options.

To list all processes using PowerShell, the command is:

Get-Process

This command gives you a similar overview of running processes, but with more properties available for each process. Comparing the outputs from PowerShell and CMD can help you learn the nuances of each tool.

Using WMIC to List Processes

The WMIC (Windows Management Instrumentation Command-line) tool provides another alternative for listing processes, often favored for more advanced queries.

To obtain a list of processes along with their names and process IDs, you can use:

wmic process get name,processid

This command gives you a simplified output, focusing on the essential attributes of each process, providing clarity when managing processes.

WMIC Process List: How to Find All Running Processes

When managing a Windows environment, understanding the processes running on the system is critical for performance monitoring, troubleshooting, and security management. One of the most powerful and versatile tools available for Windows administrators is the Windows Management Instrumentation Command-line (WMIC). In this article, we will delve into the WMIC process list, demonstrating how to effectively utilize it to find all running processes, gain insights into their behavior, and enhance your overall system management capabilities.

Understanding WMIC

Windows Management Instrumentation (WMI) is a Microsoft technology that allows for the management and monitoring of system hardware, software, and services in Windows-based environments. WMIC is a command-line interface that provides a way to interact with WMI without writing complex code. With WMIC, users can query information about the operating system, hardware, software, and various system metrics quickly and efficiently.

What is a Process?

In computing, a process is a running instance of a program that includes the program code, its current activity, and any associated resources like memory, file handles, and security attributes. Windows, like many modern operating systems, is multitasking and can handle multiple processes simultaneously. Understanding running processes can help diagnose performance issues, detect unauthorized software, and manage resource allocation.

Accessing WMIC

To begin using WMIC, you need to access the Command Prompt in Windows. Here’s how to do that:

Open the Command Prompt:
- Press Windows Key + R, type cmd, and hit Enter.
- Alternatively, you can search for «Command Prompt» in the start menu.
Launch WMIC:
- Simply type wmic and hit Enter to enter the WMIC command line.

Getting the Process List with WMIC

To retrieve a list of all running processes on a Windows machine using WMIC, you can use the following command:

wmic process list

This command will display a tabular list of all processes currently running on the system, along with relevant details such as:

Process ID (PID): A unique identifier assigned by the operating system to each running process.
Name: The executable name of the process.
Command Line: The command that was used to start the process.
Status: The current status of the process (e.g., Running, Stopped).
User: The user account under which the process is running.
Memory Usage: The amount of memory (in kilobytes) being utilized by the process.

Filtering Process Information

By default, the output from the wmic process list command may be extensive. To filter the results and retrieve specific processes, you can employ the /format switch or use query capabilities in WMIC.

Example 1: Filtering by a Specific Process Name

To find a process with a specific name, let’s say notepad.exe, you can execute the following command:

wmic process where "name='notepad.exe'" get ProcessId, Caption, CommandLine

This would return just the PID, name, and command line of the Notepad process if it is running.

Example 2: Querying for High Memory Usage Processes

To identify processes consuming a significant amount of memory, you might want to filter for processes where the working set size (memory usage) is above a certain threshold. This can also be achieved with WMIC:

wmic process where "WorkingSetSize > 104857600" get ProcessId, Caption, WorkingSetSize

In this example, 104857600 represents the memory size in bytes (100 MB).

Common WMIC Process Commands

Besides listing processes, WMIC provides a suite of commands that allow users to perform various operations on the processes:

Killing a Process:
If you need to terminate a runaway process, you can do so using:
```
wmic process where "name='notepad.exe'" call terminate
```
This would forcefully close Notepad and free up system resources.
Getting More Detailed Information:
Sometimes you may want more details about a particular process. You can:
```
wmic process where "ProcessId=1234" get /format:list
```
Replace 1234 with the actual PID of the process you’re interested in. This command will provide detailed information about the specified process.
Starting a New Process:
You can even use WMIC to create a new process:
```
wmic process call create "notepad.exe"
```
This command will launch a new instance of Notepad.

Exploring WMIC Output Format

The WMIC output can be formatted in various ways for easier readability. The /format switch allows you to display data in different formats such as table, csv, list, and more.

Example displaying processes in CSV format:

wmic process list /format:csv

Using the CSV format can be particularly useful when pouring data into Excel or other analysis software for further investigation.

WMIC Process List vs. Task Manager

While WMIC is a powerful tool for process monitoring, many users are accustomed to using the Task Manager for similar purposes. Each approach has its pros and cons:

Task Manager is user-friendly with a graphical interface, providing real-time updates, easy navigation, and options to interact with processes (like stopping and starting processes) in a visual manner. It’s easily accessible via Ctrl + Shift + Esc.
WMIC, on the other hand, is more suited for command-line enthusiasts and allows for automation through scripts, making it ideal for system administrators. It provides deeper access to system information that may not be as readily available through the Task Manager.

Automating WMIC Commands

For system administrators, automating the monitoring of processes can lead to significant enhancements in efficiency. You can write script files (batch files or PowerShell scripts) that run WMIC commands at set intervals or in response to specific events.

Example of a Batch File:

Create a text file (with a .bat extension) containing the following lines:

@echo off
echo Checking running processes...
wmic process list
pause

When executed, this batch file will call WMIC to list the processes and wait for user input before closing, allowing administrators to see the output conveniently.

Best Practices for Using WMIC Process List

Run as Administrator: Some WMIC commands require elevated privileges. Always run your command prompt as an administrator to avoid permission issues.
Avoid Using Wildcards in Queries: While wildcards may work for queries, they may yield unpredictable results. It’s best to specify exact names when performing actions on processes.
Regularly Monitor Critical Processes: Automate the monitoring and logging of processes that are critical for your server or application. This can help you stay ahead of potential performance issues.
Script for Recurring Tasks: If you frequently perform certain queries or tasks via WMIC, consider scripting them. This saves time and ensures consistency.
Keep Security in Mind: When terminating processes or modifying them, ensure you’re aware of what each process does to avoid disrupting critical system functions.

Conclusion

The WMIC process list is an invaluable tool for anyone looking to manage and monitor processes within a Windows environment. Whether you’re troubleshooting an issue, investigating performance bottlenecks, or conducting security audits, WMIC provides straightforward access to essential process data.

With its command-line interface, WMIC enables more flexibility and scripting capabilities than traditional GUI tools like Task Manager. By understanding how to access and utilize the information provided by WMIC, you can improve your efficiency in managing the Windows operating system, allowing for proactive measures when assessing system health and performance.

As a final note, while WMIC is powerful, remember that Microsoft is gradually transitioning from WMIC to PowerShell for system administration. Learning PowerShell commands can provide even more powerful capabilities for managing processes and systems. However, for quick tasks and traditional environments, mastering WMIC remains a highly relevant skill.
