Why Knowing Your PowerShell Version Matters

Updated on July 3, 2025, by ITarian

Ever asked yourself, “What version of PowerShell do I have?” You’re not alone. Whether you’re running scripts, managing servers, or deploying enterprise configurations, knowing your exact PowerShell version is crucial.

This guide shows you how to show PowerShell version using various methods—from basic commands to cross-platform checks. Designed for cybersecurity professionals, IT managers, and developers, this walkthrough ensures your scripts run smoothly and securely across all systems.

What Is PowerShell, and Why Does Version Matter?

PowerShell is a command-line shell and scripting language built for task automation and configuration management. With every new version, Microsoft introduces powerful features, security updates, and cross-platform support.

Knowing your PowerShell version helps you:

• Ensure script compatibility

• Access new cmdlets and features

• Stay up to date with security patches

• Troubleshoot environment-specific issues

⚠️ Some modules require a minimum version of PowerShell to function properly—especially in enterprise automation.

How to Show PowerShell Version (4 Reliable Methods)

Method 1: Using $PSVersionTable

This is the most direct and widely-used method.

Steps:

1. Open PowerShell.

Type the following command:

powershell
CopyEdit
$PSVersionTable

This displays a detailed table with:

• PSVersion (your actual PowerShell version)

• PSEdition (Desktop or Core)

• CLRVersion

• OS

✅ This method is compatible with both Windows PowerShell and PowerShell Core.

Method 2: Get Only the Version Number

If you need just the version number:

powershell

CopyEdit

$PSVersionTable.PSVersion

This returns a clean version string like 5.1.19041.2364.

🔍 Ideal for scripts or documentation where you only need the version field.

Method 3: Using Get-Host Command

Another way to check PowerShell version is via host information:

powershell

CopyEdit

Get-Host | Select-Object Version

This returns the version of the host application, which often aligns with your PowerShell version.

📌 Use this in environments where $PSVersionTable is restricted or overridden.

Method 4: PowerShell Version Check via Script

To automate version checks across devices:

powershell

CopyEdit

if ($PSVersionTable.PSVersion.Major -lt 5) {

  Write-Output “Please upgrade PowerShell to version 5 or later.”

} else {

  Write-Output “PowerShell version is up to date.”

}

🤖 Great for IT admins managing large enterprise networks.

Windows PowerShell vs. PowerShell Core

💡 If you’re running cross-platform scripts or working in hybrid cloud environments, PowerShell Core is the way forward.

Checking PowerShell Version on Different Platforms

On macOS/Linux

Open your terminal and type:

bash

CopyEdit

pwsh

Then, in PowerShell:

powershell

CopyEdit

$PSVersionTable

PowerShell Core (v6+) is required on non-Windows platforms.

On Windows via Command Prompt

In Command Prompt, type:

cmd

CopyEdit

powershell -command “$PSVersionTable.PSVersion”

Useful for remote checks or when scripting across environments.

When Should You Upgrade PowerShell?

Upgrading to the latest version is essential when:

• You’re running scripts that fail due to missing cmdlets

• You require better security and encryption standards

• You’re working with cloud-based services like Azure or Microsoft 365

🛠️ PowerShell 7+ supports improved error handling, pipeline parallelism, and native compatibility with SSH.

FAQs About PowerShell Version Checks

Q1: What version of PowerShell do I have by default in Windows 10/11?

Windows 10 and 11 usually ship with PowerShell 5.1. Newer systems may have PowerShell 7 if installed manually.

Q2: Is PowerShell Core the same as Windows PowerShell?

No. PowerShell Core is cross-platform and open-source. Windows PowerShell is legacy and Windows-only.

Q3: Can I have multiple PowerShell versions installed?

Yes. PowerShell Core installs side-by-side with Windows PowerShell without conflict.

Q4: What is the difference between $PSVersionTable and Get-Host?

$PSVersionTable provides complete environment info. Get-Host shows the host shell’s version, which might differ in embedded systems.

Q5: How do I upgrade PowerShell safely?

Visit the official GitHub PowerShell releases page or use the Windows Package Manager (winget) to install the latest version.

Final Thoughts: Stay Ahead with the Right PowerShell Version

Understanding how to show PowerShell version isn’t just about tech specs—it’s about security, reliability, and compatibility. As automation and scripting continue to dominate IT workflows, using the correct version helps prevent errors and enhances productivity.
