5 Essential Steps to Uninstall a PowerShell Module: An Expert Guide
Imagine you’re working on a crucial project and find that one of the PowerShell modules you’ve installed is causing issues or is no longer needed. You start searching for ways to uninstall the module, but you feel overwhelmed by the hundreds of search results that don’t seem to provide a clear answer. Your time is valuable, and you need a quick yet reliable solution.
In this article, we’ll walk you through five essential steps to uninstall a PowerShell module, ensuring a clean removal and avoiding potential issues. We’ll also cover secondary keywords and other useful information on managing your PowerShell environment.
1. Identify the Modules
Before you can uninstall a module, you must first identify it in your system. To do so, use the `Get-Module` cmdlet with the `-ListAvailable` parameter:
“`powershell
Get-Module -ListAvailable
“`
This command will display a list of all installed modules and their detailed information. Look for the module you want to remove and note its name.
2. Check for Dependencies
To avoid breaking your scripts or other functionalities, it’s essential to check if the module you plan to remove has any dependencies. You can use the `Find-Module` cmdlet from `PowerShellGet` to check for dependencies:
“`powershell
# Replace ‘ModuleName’ with the actual module name
Find-Module -Name ‘ModuleName’ | Select-Object -ExpandProperty Dependencies
“`
If you see any dependencies, consider uninstalling or updating them before proceeding.
3. Uninstall the Module
Now that you’ve identified the module and checked for dependencies, you can proceed with the uninstallation. Use the `Uninstall-Module` cmdlet to remove the module:
“`powershell
# Replace ‘ModuleName’ with the actual module name
Uninstall-Module -Name ‘ModuleName’
“`
This command will uninstall the specified module from your system.
Pro tip: If you encounter any issues during the uninstallation process, try running the command with elevated privileges by opening PowerShell as an administrator.
4. Verify the Module Uninstallation
After the module has been uninstalled, it’s crucial to verify its removal to avoid leaving behind any residual files or settings. You can do this by running the `Get-Module` cmdlet again with the `-ListAvailable` parameter:
“`powershell
Get-Module -ListAvailable
“`
If the module is no longer listed, the uninstallation was successful.
5. Clean Up Module Files (Optional)
In some cases, there might be residual files left after uninstalling a module, such as configuration files or other data stored in the `%UserProfile%DocumentsWindowsPowerShellModules` folder. To ensure a thorough removal of the module, you can manually delete these files:
“`powershell
# Replace ‘ModuleName’ with the actual module name
Remove-Item -Recurse -Force “$($env:USERPROFILE)DocumentsWindowsPowerShellModulesModuleName”
“`
This command will remove any leftover files for the specified module.
By following these five essential steps, you can quickly and effectively uninstall a PowerShell module, ensuring that your environment remains clean and organized.

Now that you know how to uninstall a PowerShell module, let’s touch upon secondary keywords and other useful tips for managing your PowerShell environment:
– Update a module: To update an existing module, use the `Update-Module` cmdlet:
“`powershell
# Replace ‘ModuleName’ with the actual module name
Update-Module -Name ‘ModuleName’
“`
– Check for module updates: To check if updates are available for a specific module, use the `Find-Module` and `Get-InstalledModule` cmdlets:
“`powershell
# Replace ‘ModuleName’ with the actual module name
$Latest_Module_Version = (Find-Module -Name ‘ModuleName’).Version
$Installed_Module_Version = (Get-InstalledModule -Name ‘ModuleName’).Version
if ($Latest_Module_Version -gt $Installed_Module_Version) {
Write-Host “An update is available for the module.”
} else {
Write-Host “The module is up-to-date.”
}
“`
In conclusion, by following the steps outlined in this expert guide, you will be able to successfully uninstall a PowerShell module from your system. Keep these practices in mind while managing your PowerShell environment for smooth operations and efficient scripting.

What is the method for fully removing PowerShell?
Fully removing PowerShell from a system is not recommended, as it is an integral part of Windows and many other applications rely on it. However, if you really need to remove PowerShell, you can uninstall the specific version. It’s important to note that this might cause issues with your operating system and certain applications.
For Windows PowerShell 5.1 (which comes bundled with Windows), it’s not possible to fully remove it without causing damage to the system.
For newer versions of PowerShell (PowerShell 7 and above), you can uninstall them using the following steps:
1. Open the Control Panel by pressing `Win + X` and selecting it from the menu.
2. Go to Programs and Features.
3. Locate the PowerShell 7.x entry in the list of installed programs (_x_ denotes the specific version number).
4. Select the PowerShell 7.x entry and click on Uninstall.
5. Follow the prompts in the uninstallation wizard to completely remove PowerShell from your system.
Remember, attempting to remove or disable PowerShell may lead to a non-functional state or unintended behavior in your operating system or applications.
How can I remove PowerShell using the command prompt?
If you wish to remove PowerShell from your system using the command prompt, follow these steps:
For Windows PowerShell:
1. Open the Command Prompt with administrative privileges by pressing Win+X and selecting “Command Prompt (Admin)” or “Windows PowerShell (Admin)”.
2. Type the following command and press Enter:
“`
wusa /uninstall /kb:3177186 /quiet /norestart
“`
This command will uninstall the Windows Management Framework, which includes PowerShell.
Note: It is important to mention that removing PowerShell from your system can cause issues with some programs and features that rely on it. Be cautious when removing it, and consider creating a backup before proceeding.
For PowerShell 7 and later versions:
1. Open the Command Prompt with administrative privileges by pressing Win+X and selecting “Command Prompt (Admin)” or “Windows PowerShell (Admin)”.
2. Identify the package name by running the following command:
“`
wmic product where “name like ‘PowerShell%'” get Name, Version, IdentifyingNumber
“`
3. Look for PowerShell 7 or the specific version you want to remove in the output and note its `IdentifyingNumber`.
4. Uninstall PowerShell using the following command with the obtained `IdentifyingNumber`:
“`
msiexec /x {IdentifyingNumber} /qn /norestart
“`
For example, to remove PowerShell 7.x, the command would look like this:
“`
msiexec /x {07F10AB0-99B5-11EA-A2E2-F34A121CCE65} /qn /norestart
“`
This will silently uninstall PowerShell 7.x without restarting your system. Remember to replace the `IdentifyingNumber` with the one you found in step 3.
How can I uninstall a package in Windows 10 using PowerShell?
To uninstall a package in Windows 10 using PowerShell, you can use the Get-AppxPackage and Remove-AppxPackage cmdlets. Follow these steps:
1. Open an elevated PowerShell window. To do this, press the Windows key, type “PowerShell”, right-click on “Windows PowerShell”, and select “Run as administrator”.
2. Find the full package name of the application you want to uninstall by running the following command:
“`
Get-AppxPackage | Select Name, PackageFullName
“`
This will display a list of installed packages with their names and full package names (also known as PackageFamilyName).
3. Locate the package you want to uninstall in the list and copy its PackageFullName.
4. Run the following command to uninstall the package:
“`
Remove-AppxPackage -Package [PackageFullName]
“`
Replace [PackageFullName] with the actual package name that you copied in step 3.
For example, to uninstall Microsoft Paint, the command would look like this:
“`
Remove-AppxPackage -Package Microsoft.MSPaint_23.0.23.0_x64__8wekyb3d8bbwe
“`
5. The package should now be uninstalled. You can close the PowerShell window.
Please note that some built-in or system apps cannot be uninstalled using this method.
What is the most efficient method to uninstall a PowerShell module from the command-line?
The most efficient method to uninstall a PowerShell module from the command-line is by using the Uninstall-Module cmdlet. This cmdlet removes the specified module from the system.
To do this, open a new PowerShell window with administrator privileges and run the following command:
“`powershell
Uninstall-Module -Name
“`
Replace “ with the name of the module you want to uninstall.
For example, if you want to uninstall a module called “SampleModule”, you would run:
“`powershell
Uninstall-Module -Name SampleModule
“`
Keep in mind that some modules might have dependencies, so you may need to uninstall them as well. Also, make sure you close all active PowerShell sessions before running this command to avoid any issues with locked files.
How can I identify and remove multiple or outdated versions of a PowerShell module using command-line tools?
You can identify and remove multiple or outdated versions of a PowerShell module using the command-line tools by following these steps:
Step 1: Identify installed PowerShell modules and their versions
To list all the installed PowerShell modules and their versions, use the following command:
“`powershell
Get-InstalledModule | Select-Object Name, Version
“`
Step 2: Find multiple or outdated versions of a specific module
To find multiple or outdated versions of a specific module, you can filter the results from Step 1 by the module name. For example, let’s say you want to check for multiple versions of the ‘AzureRM’ module:
“`powershell
Get-InstalledModule | Where-Object { $_.Name -eq ‘AzureRM’ } | Select-Object Name, Version
“`
Step 3: Remove outdated versions of the module
Once you have identified the outdated version(s) of the module, you can remove them using the `Uninstall-Module` command. Replace ‘ModuleName’ with the actual module name and ‘VersionNumber’ with the version you want to remove:
“`powershell
Uninstall-Module -Name ‘ModuleName’ -RequiredVersion ‘VersionNumber’
“`
For example, to remove version 5.0.0 of the ‘AzureRM’ module:
“`powershell
Uninstall-Module -Name ‘AzureRM’ -RequiredVersion ‘5.0.0’
“`
Repeat this step for each outdated version you want to remove.
By using these command-line tools, you can quickly and easily identify and remove multiple or outdated versions of a PowerShell module from your system.
Are there any best practices or precautions to consider when uninstalling a PowerShell module from the command-line?
Yes, there are several best practices and precautions to consider when uninstalling a PowerShell module from the command-line. Here are some important points:
1. Backup your data: Before uninstalling any module, ensure that you have backed up any data, configurations, or settings related to the module. This will help you restore your configuration in case you need to reinstall it later.
2. Check dependencies: Some modules may have dependencies on other modules or components. Ensure that you understand the dependencies for any module you plan to uninstall, as removing a module could cause issues with dependent modules. Use the `Get-Module` cmdlet with the `-ListAvailable` flag to view installed modules and their dependencies.
3. Close open sessions: If you are uninstalling a module that is currently in use, make sure to close any open PowerShell sessions or processes using the module. Failure to do so can lead to inconsistencies and errors during the uninstallation process.
4. Use the correct cmdlet: To uninstall a module, use the `Uninstall-Module` cmdlet. This cmdlet uninstalls a module only if it is installed in a location specified in the `$env:PSModulePath`. For older versions of PowerShell that do not have this cmdlet, you may manually delete the module folder from the appropriate path.
Example:
“`powershell
Uninstall-Module -Name ModuleName
“`
5. Administrator privileges: Ensure that you have administrator privileges when uninstalling a module. This is necessary to avoid permission issues that could prevent successful uninstallation.
6. Be cautious with shared environments: In a shared environment, be careful while uninstalling a module as it might affect other users or systems that rely on that module. Coordinate with your team and make sure everyone is aware of the changes.
7. Test in a non-production environment: If possible, test the uninstallation process in a non-production environment to make sure that it won’t cause any issues or errors. This can help you identify potential problems before applying the changes to a production environment.
8. Documentation: Always document the modules you have uninstalled, as well as any changes made to the system as a result. This will help you keep track of your system’s configuration and make it easier to troubleshoot issues in the future.
