The Windows operating system has many active processes and services that start up after the system boots. Some core system processes start automatically, while others are created when you launch the application. Each process has a process ID (PID) as a unique identifier.
You can use the PID to identify the correct subprocess, or use it to debug if it is consuming system resources or acting confusingly. Here are several ways to find the process ID of an application on your system.
1. Use Task Manager
The Task Manager provides a graphical user interface to display information about system processes and services. The latest version of Task Manager for Windows 11 has added a search feature. So it becomes easier to locate active processes by their name or process ID. This is the way:
1. Right-click the Start button to open the Power User menu. Click the Task Manager option in the menu.
2. Go to the left menu and click the Details tab.
3. You should see the Process ID column appear next to the process name. You can check and copy the process ID.
4. Alternatively, you can view the PID from the Process tab. Task Manager does not show process IDs by default. So you have to add the PID column in Process tab.
5. Right-click on any column in the Process tab and select the PID option from the context menu.
6. Now you can see the related PID of each process.
2. Use Resource Monitor
Windows Resource Monitor provides a detailed view of the system resources being used. You can get detailed information about the modules that the active process relies on to function properly. It also presents a graphical view of the resource consumption of the system hardware (CPU, Memory, Disk and Network). But you can also find the PID of any process in this utility. This is the way:
1. Press the Windows key to open the Start menu, type resmon.exethen press Enter.
2. In the Resource Manager window, click the Storage tab.
The Memory section will show all running processes with their respective PIDs. But you cannot copy the PID directly from the column.
3. Using the Command Prompt
For terminal lovers, it is possible to view the PID of a process using the Command Prompt. By default, the Command Prompt opens in the Terminal application window. Repeat the following steps:
1. Right-click the Start button to launch the Power User menu. Click the Terminal option from the list.
2. Type the following command and press Enter to list all active processes with their PIDs:
Task list
3. The output of the tasklist command can be hard to read and difficult to navigate in a Terminal window. Therefore, you can copy the results to a text file for convenience. Type the following command into the Command Prompt window and press Enter:
Task List > D:\PIDfile.txt
4. The above command will save all the output items of the tasklist command to a text file named PIDfile.
4. Using PowerShell
Like the Command Prompt, you can use the PowerShell cmdlet to list the processes running on your system. You can display all processes, their respective process IDs and other available parameters. This is the way:
1. Press the Windows key to open the Start menu, type PowerShelland then press Enter to launch the tool.
2. PowerShell will open inside the Terminal application window. Type the following command and press Enter to generate a list of running processes and their PIDs:
Get-Process | Format-Table -Property ProcessName,Id
3. We have intentionally limited the output to two columns. Viewing PIDs and names just got easier. But if you are still having trouble navigating the terminal window, you can copy the output of the Get-Process command to a CSV file. Type the following command and press Enter:
Get-Process | Format-Table -Property ProcessName,Id > D:\q.csv
4. You can use File Explorer to locate the newly created CSV file in drive D. Open it in Excel to view and search for a specific PID.
5. Using Third Party Tools
The inbuilt task manager may seem a bit lacking for advanced users. So you can use a third party tool like Process Explorer or Process Lasso to check the PID of any process. But Process Lasso can do more than just enumerate system stats. You can use it to improve system performance, take full control of processes and log all that data. Here’s how to check the PID using Process Lasso:
1. Download and install Process Lasso application on your system.
2. Launch the app and click the View option. Uncheck the Show Graph and Tree View options in the View menu.
3. You can view all the processes, their process IDs and a lot of information related to the process, including its location, in one window. No need to switch tabs.
Find PID at a glance
Windows assigns a PID to every running process. No two processes can have the same PID. The PID is temporary and your computer will assign a new decimal value every time you close and restart any application.
