how to update powershell version with code examples

PowerShell is a powerful tool that is extensively used by system administrators and developers. It is a command-line-based shell and scripting language, which is built on the .NET Framework. Microsoft frequently releases new versions of PowerShell, which includes new features, improvements, and bug fixes. In this article, we will discuss how to update the PowerShell version with code examples.

Before we move forward, let's take a quick review of the current version of PowerShell. As of the time of this writing, PowerShell 7.1 is the latest version. However, PowerShell 5.1 is the default version that comes pre-installed in most of the Windows operating systems. It's important to note that PowerShell 7 is a cross-platform version that supports Linux, macOS, and Windows.

Steps to Updating PowerShell Version:

Step 1: Determine the Current PowerShell Version

Before updating, it's essential to determine the current PowerShell version installed on your system. To check the version, open the PowerShell console and type the command:

$PSVersionTable

This command prints out the table of information containing the PowerShell version, build number, CLR version, and other details.

Step 2: Download and Install the Latest PowerShell Core

The PowerShell Core is the cross-platform variant of PowerShell, which is regularly updated by Microsoft. To get the latest version, visit the official PowerShell downloads page, and download the latest version for your operating system. Choose the package according to your operating system and architecture.

Step 3: Install the PowerShell Core with Window PowerShell Compatibility Module (Windows)

After downloading the PowerShell Core, it's time to install it on your system. For Windows, PowerShell Core can be installed with the help of the Windows PowerShell Compatibility Module.

Install-Module -Name PowerShellGet -Force -Scope CurrentUser
Install-Module -Name PackageManagement -Force -Scope CurrentUser
Install-Module -Name PowerShellCompatibilityLayer -Force -Scope CurrentUser

This code installs the PowerShellGet, PackageManagement, and PowerShellCompatibilityLayer modules, which are required for the installation of PowerShell Core.

Step 4: Set the PowerShell Core as the Default Version

After installation, you need to set the PowerShell Core as your default version. To achieve this, you have to open the Windows PowerShell as an administrator and run the following command:

Set-ExecutionPolicy RemoteSigned

This command allows the running of scripts on your system. Then, run the following command for setting the PowerShell Core as the default version:

Set-ItemProperty -Path 'HKLM:\Software\Microsoft\Windows\CurrentVersion\WSMAN\Client' -Name 'DefaultShell' -Value 'pwsh.exe'

This code sets the default shell to the pwsh.exe file, which is the core PowerShell executable.

Example: Updating PowerShell version from 5.1 to 7.1

Now that we have seen the steps for updating PowerShell version let's see an example of updating PowerShell from version 5.1 to 7.1. Follow these steps:

  1. First, check the current PowerShell version with the following command:
$PSVersionTable.PSVersion

It shows the current PowerShell version, i.e., version 5.1.

  1. Download the latest PowerShell version from the official downloads page.

  2. Install the downloaded file on your system.

  3. After installation, open the PowerShell console as an administrator.

  4. Run the following command:

Set-ExecutionPolicy RemoteSigned
  1. Then, enter the following command to set the PowerShell Core as the default version:
Set-ItemProperty -Path 'HKLM:\Software\Microsoft\Windows\CurrentVersion\WSMAN\Client' -Name 'DefaultShell' -Value 'pwsh.exe'
  1. After that, close the PowerShell console and reopen it. Type the following command to check the latest PowerShell version:
$PSVersionTable.PSVersion

This command shows the updated PowerShell version, i.e., version 7.1.
