In the sections ahead, we’ll explore straightforward methods to quickly determine your Windows PowerShell version. Whether you prefer graphical interfaces or command-line techniques, you’ll find easy-to-follow approaches that fit your style. By the end, you’ll be equipped with the know-how to check your PowerShell version effortlessly, setting the stage for more effective scripting and system management.

Checking PowerShell Version Using Command Line

To determine the installed version of Windows PowerShell, you can use several built-in commands executed directly in a PowerShell session. This method is efficient and provides detailed version information without needing administrative privileges.

The most common command to retrieve the PowerShell version is:

“`powershell
$PSVersionTable.PSVersion
“`

This command returns a structured object that contains the major, minor, build, and revision numbers of the PowerShell version currently running. For example, the output might look like this:

“`
Major Minor Build Revision
—– —– —– ——–
5 1 19041 1151
“`

Additional Properties in `$PSVersionTable`

The `$PSVersionTable` automatic variable contains more than just the PowerShell version number. It also includes information about the environment, such as the CLR version, platform, and edition. You can display the entire table by simply entering:

“`powershell
$PSVersionTable
“`

This provides a broader context useful for troubleshooting or compatibility checks.

Alternative Commands to Check Version

  • `Get-Host | Select-Object Version`: Returns the version of the host application running PowerShell, which might differ from the engine version.
  • `[System.Environment]::OSVersion.Version`: Provides the operating system version, which can help correlate PowerShell versions with OS builds.
  • `powershell -version`: When run from Command Prompt, it can launch PowerShell with a specific version or display the version information.

Summary of Common Commands

Command Description Output Type
$PSVersionTable.PSVersion Retrieves detailed PowerShell engine version information. PSVersion object (Major, Minor, Build, Revision)
$PSVersionTable Displays complete environment and version details related to PowerShell. Hashtable
Get-Host | Select-Object Version Shows the host application’s version of PowerShell. System.Version object
powershell -version Displays version info when run from Command Prompt or specifies version on launch. String (console output)

Using PowerShell ISE or Scripts to Identify Version

For users who prefer working within the PowerShell Integrated Scripting Environment (ISE) or want to include version checks within scripts, the same `$PSVersionTable.PSVersion` property is invaluable.

Embedding a version check in a script can help manage compatibility by conditional execution based on the version detected. For instance:

“`powershell
if ($PSVersionTable.PSVersion.Major -lt 5) {
Write-Host “Please upgrade your PowerShell version to 5.0 or higher.”
exit
}
else {
Write-Host “PowerShell version is compatible.”
}
“`

This script snippet verifies if the major version is less than 5 and prompts the user accordingly, preventing the script from running on incompatible versions.

Automation and Reporting

Scripts can be designed to collect version information from multiple remote machines using remoting features:

“`powershell
Invoke-Command -ComputerName Server01,Server02 -ScriptBlock {
$PSVersionTable.PSVersion
}
“`

This command queries the PowerShell version on specified remote computers, which is especially useful for administrators managing large environments.

Key Points for Script-Based Version Checks

  • Always check the Major and Minor version numbers for compatibility.
  • Consider build and revision numbers when precise feature availability is critical.
  • Use conditional statements to prevent execution on unsupported versions.
  • Implement remote version checks to manage multiple systems efficiently.

Checking PowerShell Version via Windows Settings and System Information

While command-line methods are most direct, some users may want to verify PowerShell version through Windows system tools or settings.

Windows Features and Installed Programs

PowerShell versions are tied to the Windows version or installed updates, so you can:

  • Check the **Windows version** via `winver` command or System Information (`msinfo32`).
  • Look into **Installed Updates** in Control Panel to identify PowerShell updates or upgrades.
  • Review installed **Windows Features** to confirm whether Windows PowerShell 2.0 or later is enabled.

Using System Information Tool

Open System Information and navigate to **Software Environment > Environment Variables or System Summary** to find relevant details, although direct PowerShell version info might not be explicitly listed.

Version Mapping Table for Windows and PowerShell

Checking Windows PowerShell Version Using Command Line

To determine the version of Windows PowerShell installed on your system, you can use several command-line approaches. These methods provide quick and reliable information about your PowerShell environment.

Open PowerShell with administrative or standard privileges and enter one of the following commands:

  • $PSVersionTable.PSVersion: This is the most straightforward method and displays the major, minor, build, and revision numbers of the PowerShell version.
  • Get-Host | Select-Object Version: Returns the version of the PowerShell host, which generally corresponds to the PowerShell version.
  • $Host.Version: A property that gives the version of the current PowerShell host instance.

These commands differ slightly in output format but will provide the same essential version details.

Windows Version Default PowerShell Version Notes
Windows 7 2.0 PowerShell 2.0 installed by default; later versions require manual installation.
Windows 8 / 8.1 3.0 / 4.0 PowerShell 3.0 pre-installed; 4.0 available via Windows Management Framework.
Windows 10 (initial releases) 5.0 / 5.1 PowerShell 5.x included; updated with OS patches.
Command Purpose Sample Output
$PSVersionTable.PSVersion Displays detailed PowerShell version information Major: 5
Minor: 1
Build: 19041
Revision: 1237
Get-Host | Select-Object Version Returns the PowerShell host version Version
——-
5.1.19041.1237
$Host.Version Outputs the current PowerShell host version 5.1.19041.1237

Using PowerShell ISE or Script to Verify Version

When using the Windows PowerShell Integrated Scripting Environment (ISE), you can check the version directly within the scripting interface. This is particularly useful for developers or administrators running multiple scripts.

Within PowerShell ISE, type the following line in the script pane or command pane:

Write-Output $PSVersionTable.PSVersion

Executing this command will display the version information in the output pane, allowing you to confirm the PowerShell version without leaving the development environment.

Understanding PowerShell Version Components

The version number displayed by PowerShell typically consists of several components that provide insight into the release and build of your environment:

Component Description
Major Indicates significant changes or new features introduced in the PowerShell version.
Minor Represents smaller feature updates and improvements.
Build Specifies the build number, often linked to the specific Windows build or PowerShell release.
Revision Reflects minor fixes, patches, or revisions applied post-build.

Knowing these components helps interpret the version number and understand compatibility or feature availability.

Checking PowerShell Version via System Information Tools

In addition to command-line methods, you can confirm the PowerShell version using Windows system tools:

  • Programs and Features: Navigate to Control Panel > Programs > Programs and Features and look for Windows Management Framework entries, which include PowerShell updates.
  • System Environment Variables: Inspect environment variables such as PSModulePath or check registry keys under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell for installed versions.
  • Windows Settings: In Windows 10 and later, PowerShell version is often bundled with the OS version, so reviewing the OS build number can indirectly inform about PowerShell version.

Using PowerShell Version in Scripts for Compatibility Checks

When writing PowerShell scripts intended for diverse environments, verifying the PowerShell version at runtime ensures compatibility and prevents execution errors.

Example script snippet to check version before executing version-dependent code:

if ($PSVersionTable.PSVersion.Major -ge 5) {
    Execute code requiring PowerShell 5.0 or higher
} else {
    Write-Warning "This script requires PowerShell version 5.0 or higher."
}

This conditional logic helps maintain script robustness across varying system configurations.
