Process management (Get/Stop-Process) in PowerShell

Introduction

Process management helps you see and control programs running on your computer. You can find and stop programs easily.

You want to check if a program is running before starting it again.

You need to stop a program that is frozen or not responding.

You want to see all running programs to understand what your computer is doing.

You want to stop a background task that is using too much memory.

You want to automate closing certain programs at a specific time.

Syntax

PowerShell

Get-Process [-Name <string[]>] [-Id <int[]>]
Stop-Process [-Name <string[]>] [-Id <int[]>] [-Force]

Get-Process shows running programs by name or ID.

Stop-Process stops a program by name or ID. Use -Force to stop it immediately.

Examples

Shows all running processes on your computer.

PowerShell

Get-Process

Shows only the Notepad program if it is running.

PowerShell

Get-Process -Name notepad

Stops the Notepad program safely.

PowerShell

Stop-Process -Name notepad

Forces the process with ID 1234 to stop immediately.

PowerShell

Stop-Process -Id 1234 -Force

Sample Program

This script shows all running Notepad processes, stops them, then tries to show them again to confirm they stopped.

PowerShell

Write-Host "List of running Notepad processes:"
Get-Process -Name notepad

Write-Host "Stopping all Notepad processes..."
Stop-Process -Name notepad

Write-Host "Notepad processes after stopping:"
Get-Process -Name notepad -ErrorAction SilentlyContinue

Important Notes

If you try to stop a process that is not running, PowerShell shows an error unless you use -ErrorAction SilentlyContinue.

Use Get-Process to find the exact name or ID of the process before stopping it.

Stopping system processes can cause your computer to crash. Only stop processes you know.

Summary

Get-Process shows running programs by name or ID.

Stop-Process stops programs safely or forcefully.

Use these commands to control programs running on your computer easily.
