PowerShell Process Management

last modified February 15, 2025

This tutorial covers essential PowerShell commands for managing system processes. Learn to view, stop, and control applications and services through cmdlets.

Processes are running program instances consuming system resources. PowerShell provides powerful commands to interact with processes for system administration.

Listing Processes

Use Get-Process to retrieve information about running processes:

processes.ps1

Get-Process

This command displays all active processes with details like ID, CPU usage, and memory consumption. Add process names as parameters to filter results.

Get-Process

Executing without parameters lists all running processes in a table format. Columns include Handles, CPU, and ProcessName.

PS C:> .\processes.ps1

Handles NPM(K) PM(K) WS(K) CPU(s) Id SI ProcessName

435      25    62248      70972       1.58   9360   2 chrome
258      15    15244      27208       0.09   4788   2 explorer

Stopping Processes

Terminate processes using Stop-Process. Always exercise caution when stopping system processes.

stop_process.ps1

Stop-Process -Id 1234 -Force Stop-Process -Name “notepad” -Force

The first command stops a process by ID, while the second terminates all instances of a named process. The -Force parameter ensures immediate termination.

-Id 1234

Specifies the process ID to terminate. Obtain IDs using Get-Process.

-Name “notepad”

Targets all processes with the specified name. Wildcards are supported for partial matches.

Starting Processes

Launch applications with Start-Process:

start_process.ps1

Start-Process notepad -PassThru

This starts Notepad and returns a process object. The -PassThru parameter enables further manipulation of the new process.

-PassThru

Returns a process object for the newly created process, allowing property access or piping to other commands.

Filtering Processes

Combine Get-Process with Where-Object for advanced filtering:

filter_processes.ps1

Get-Process | Where-Object {$_.CPU -gt 100}

This pipeline shows processes using more than 100 seconds of CPU time. Adjust the comparison value for different thresholds.

{$_.CPU -gt 100}

Filters processes where the CPU property exceeds 100 seconds. The $_ variable represents current pipeline object.
