How to Use Windows PowerShell in Windows 11

Windows PowerShell is a powerful command-line shell and scripting language designed for system administration and automation. It allows users to automate tasks, manage system configurations, and perform administrative tasks with ease. This guide will walk you through the basics of using Windows PowerShell in Windows 11.


Windows PowerShell is a versatile tool that goes beyond the traditional Command Prompt, offering advanced scripting capabilities and access to a wide range of system management tasks. Whether you're a system administrator or a power user, learning to use PowerShell can greatly enhance your ability to manage Windows 11. Follow this guide to get started with Windows PowerShell.

Step 1: Open Windows PowerShell

  1. Click on the Start menu (Windows icon) at the bottom-left corner of your screen.
  2. Type "PowerShell" in the search bar.
  3. Click on Windows PowerShell to open it. Alternatively, you can right-click and select Run as administrator to open it with administrative privileges.

Step 2: Understanding the PowerShell Interface

  1. The PowerShell interface consists of a command-line prompt where you can type commands and execute scripts.
  2. The default prompt looks like this:
    PS C:\Users\YourUsername>

Step 3: Basic PowerShell Commands

  1. Get-Help: Displays help information for PowerShell commands. For example, to get help for the Get-Process command:

    Get-Help Get-Process
  2. Get-Command: Lists all available PowerShell commands.

  3. Get-Process: Displays a list of running processes.

  4. Get-Service: Lists all services on your system.

  5. Set-ExecutionPolicy: Changes the user preference for the PowerShell script execution policy.

    Set-ExecutionPolicy RemoteSigned
  6. Get-ExecutionPolicy: Displays the current script execution policy.


Step 4: Running Scripts

  1. Create a Script: Open a text editor (e.g., Notepad) and write your PowerShell script. Save the file with a .ps1 extension.

    # Example script: hello.ps1
    Write-Output "Hello, World!"
  2. Run the Script: Open PowerShell, navigate to the directory where your script is saved, and run the script by typing:


Step 5: Using Aliases

  1. PowerShell provides aliases for commonly used commands to make them easier to use. For example, ls is an alias for Get-ChildItem.

  2. Get-Alias: Displays a list of all aliases.


Step 6: Using Modules

  1. Get-Module: Lists all installed modules.

    Get-Module -ListAvailable
  2. Import-Module: Imports a module into your session.

    Import-Module <ModuleName>
  3. Find-Module: Finds modules from the PowerShell Gallery.

    Find-Module <ModuleName>
  4. Install-Module: Installs a module from the PowerShell Gallery.

    Install-Module <ModuleName>

Step 7: Managing Files and Directories

  1. Get-ChildItem: Lists the contents of a directory.

  2. New-Item: Creates a new file or directory.

    New-Item -Path "C:\Example" -ItemType Directory
  3. Copy-Item: Copies a file or directory.

    Copy-Item -Path "C:\Example\file.txt" -Destination "C:\Example\backup\file.txt"
  4. Move-Item: Moves a file or directory.

    Move-Item -Path "C:\Example\file.txt" -Destination "C:\Example\newfile.txt"
  5. Remove-Item: Deletes a file or directory.

    Remove-Item -Path "C:\Example\file.txt"

Step 8: Advanced Features

  1. Pipeline: Passes the output of one command as input to another.

    Get-Process | Where-Object {$_.CPU -gt 100}
  2. Variables: Stores data that can be used later.

    $processes = Get-Process
  3. Loops and Conditional Statements: Performs repeated actions or checks conditions.

    # Loop example
    For ($i = 1; $i -le 5; $i++) {
        Write-Output $i
    # Conditional statement example
    If ($true) {
        Write-Output "True"
    } Else {
        Write-Output "False"

Additional Tips

  • Run as Administrator: Some PowerShell commands require administrative privileges. Right-click on PowerShell and select Run as administrator.
  • Integrated Scripting Environment (ISE): Use PowerShell ISE, an integrated scripting environment, for writing, testing, and debugging scripts. Open PowerShell ISE by typing "powershell_ise" in the Start menu search bar.
  • Error Handling: Use Try, Catch, and Finally blocks to handle errors in your scripts.
