Powershell Check If Software Is Installed

Knowing what software is installed on your computer is crucial for system management and troubleshooting. PowerShell is a powerful tool that allows you to automate this task efficiently. This guide will show you how to use PowerShell to check if software is installed on your system.

To check if the software is installed using PowerShell, run this command: Get-WmiObject -Query “SELECT * FROM Win32_Product WHERE Name = ‘SoftwareName'”. Replace ‘SoftwareName’ with the name of the software.

In this article, we will discuss “Powershell Check If Software Is Installed”.

What is PowerShell?

PowerShell is a task automation and configuration management tool from Microsoft. It includes a command-line shell and scripting language. PowerShell helps users manage computers and automate tasks, making it easier to handle system administration and configuration.

Why Use PowerShell to Check Installed Software?

Using PowerShell to check installed software is quick and efficient. It provides a list of all programs on your computer, making it easy to manage and remove unwanted software. PowerShell is a built-in tool in Windows, so you don’t need to install anything extra.

Prerequisites:

Let’s make sure you have PowerShell installed and are familiar with the basics before we get started with the commands.

1. Installing and Opening PowerShell:

PowerShell comes pre-installed on Windows 7 and later versions. To open it, simply search for PowerShell in the Start menu.
For older versions or additional features, you can download PowerShell from the Microsoft website.

2. Basic PowerShell Commands:

Get-Help: Provides help about PowerShell commands.
Get-Command: Lists all available commands.
Get-Module: Lists all installed modules.

Using PowerShell Cmdlets:

Cmdlets (pronounced “command-lets”) are lightweight commands used in the PowerShell environment. They follow a Verb-Noun naming pattern and are designed to perform a specific task.

Get-WmiObject Cmdlet:

One of the most commonly used cmdlets for checking installed software is Get-WmiObject. This cmdlet retrieves management information from local and remote computers.

Syntax: Get-WmiObject -Query “SELECT * FROM Win32_Product”.
Example: Get-WmiObject -Class Win32_Product | Select-Object -Property Name, Version.

Get-ItemProperty Cmdlet:

Another useful cmdlet is Get-ItemProperty, which can access the Windows registry to find installed software.

Syntax: Get-ItemProperty -Path “HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*” | Select-Object -Property DisplayName, DisplayVersion.
Example: Get-ItemProperty -Path “HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\*” | Select-Object -Property DisplayName, DisplayVersion.

Combining Cmdlets for Comprehensive Checks:

For a more comprehensive check, you can combine multiple cmdlets into a single script. Here’s a sample script:

$software1 = Get-WmiObject -Class Win32_Product | Select-Object -Property Name, Version
$software2 = Get-ItemProperty -Path “HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*” | Select-Object -Property DisplayName, DisplayVersion
$software3 = Get-ItemProperty -Path “HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\*” | Select-Object -Property DisplayName, DisplayVersion

$allSoftware = $software1 + $software2 + $software3
$allSoftware | Sort-Object Name | Format-Table -AutoSize

Automating Software Checks:

You can use Task Scheduler to run your PowerShell scripts at specified intervals to automate regular software checks.

Open Task Scheduler.
Create a Basic Task and follow the prompts to schedule your script.
Set the Action to start a program and browse to your PowerShell script.

Exporting Results:

Exporting the results of your software check can be useful for documentation or further analysis. You can easily export to a CSV file.

Exporting to CSV:

$allSoftware | Export-Csv -Path “C:\path\to\your\output.csv” -NoTypeInformation

Advanced Techniques:

For more advanced needs, you can leverage additional PowerShell modules and customize your scripts:

1. Using PowerShell Modules:

Modules extend the capabilities of PowerShell. For example, PSWindowsUpdate can manage Windows updates.
Install modules with Install-Module -Name ModuleName.

2. Customizing Scripts:

Tailor your scripts to specific environments or requirements.
Use parameters to make your scripts more flexible.
