7 Steps to Effectively Uninstall a PowerShell Module
It was a rainy evening, and Mary, an expert software engineer working from home, was just wrapping up her day. As she was about to shut down her computer, she noticed that her PowerShell environment was cluttered with numerous modules she no longer needed. Frustrated, she decided that it was time to clean up her workspace and uninstall those unnecessary modules. But how does one go about doing that?
This article aims to provide a comprehensive guide on how to uninstall a PowerShell module efficiently while avoiding common pitfalls. We will discuss the step-by-step process to properly remove modules and also explore secondary aspects related to uninstallation. So, let’s dive in!
_This tutorial assumes you have basic knowledge of PowerShell and module management._
1. Identifying the Module to be Uninstalled
Before you can begin the process of uninstalling a module, it is essential to identify the precise module you want to remove. To do so, simply use the following command:
“`powershell
Get-Module -ListAvailable
“`
This command will provide a list of all installed modules in your system, including their names, versions, and other relevant information.
2. Verify the Module’s Dependencies
Before proceeding further, it is crucial to ensure that the target module isn’t required by another module or script in your PowerShell environment. To verify whether the module has any dependencies or not, use the following command:
“`powershell
(Get-InstalledModule -Name ).Dependencies
“`
Replace “ with the name of the module you intend to uninstall. If there are no dependencies, proceed to the next step. However, if the module has dependencies, you might want to reconsider your decision or uninstall the dependent modules first.
3. Check the Module’s Installation Scope
PowerShell modules can be installed in one of two scopes: the _CurrentUser_ scope or the _AllUsers_ scope. The scope of the module, in this case, is essential to determine the appropriate uninstallation method.
To find out the installation scope of the module, use the following command:
“`powershell
(Get-InstalledModule -Name ).RepositorySourceLocation
“`
Replace “ with the name of the module you want to uninstall. The output will present the location where the module is installed. If the path includes `WindowsPowerShellModules`, it means the module is installed for _AllUsers_; if the path includes `DocumentsWindowsPowerShellModules`, the module is installed for the _CurrentUser_.
4. Launch PowerShell as an Administrator (If Required)
If the module you’re uninstalling was installed for _AllUsers_, you’ll need to launch PowerShell with administrator privileges. To do so, right-click on the PowerShell icon in the Start menu and select “Run as administrator”. This step is not necessary if the module was installed for the _CurrentUser_ only.
5. Uninstall the Module
Now we’re ready to uninstall the selected module. Use the following command to proceed:
“`powershell
Uninstall-Module -Name -RequiredVersion
“`
Replace “ with the name of the module you want to uninstall, and “ with the version you intend to remove. Note that you need to specify the version explicitly; otherwise, PowerShell may remove all versions of the module.
6. Verify the Module Uninstallation
To ensure that the module has been successfully uninstalled, run the `Get-Module -ListAvailable` command again. If the module doesn’t appear in the list, it means the uninstallation was successful.
7. Optional Step: Remove the Module’s Folder
In some cases, uninstalling a module using the `Uninstall-Module` command might leave its folder behind, which could lead to clutter. To delete the folder manually, navigate to the repository source location obtained in Step 3 and locate the module’s folder. Once you’ve found it, feel free to delete it.
_Remember that removing a module’s folder without using the Uninstall-Module cmdlet can cause unintended consequences and is not recommended._
With these 7 steps, Mary successfully cleared her PowerShell environment of unnecessary modules, making it tidier and more efficient. Following this guide will help you achieve the same goal when you need to uninstall a PowerShell module. So, go ahead and clean up your PowerShell workspace and make it work smoother for your future projects!

How can I fully remove PowerShell from my system?
Important Note: PowerShell is deeply integrated into the Windows operating system, and it’s not recommended to remove it completely. Doing so could cause severe issues with your system. However, if you still wish to remove PowerShell from your system, you can uninstall its newer version, PowerShell 7, but not the built-in version that comes with Windows.
To uninstall PowerShell 7, follow these steps:
1. Open Control Panel: Press Windows key + X and select Control Panel from the menu.
2. Navigate to Programs: In the Control Panel, click on Programs and Features or Uninstall a program under the Programs category.
3. Find PowerShell 7: In the list of installed programs, locate PowerShell 7 or PowerShell 7 (x64).
4. Uninstall PowerShell 7: Right-click on PowerShell 7 and select Uninstall. Follow the prompts to complete the uninstallation process.
Once again, remember that removing the built-in version of PowerShell is not recommended and can lead to stability issues with your system.
How can I remove PowerShell using the command-line?
It’s important to note that PowerShell is an integral part of the Windows operating system, and removing it might cause unexpected issues. However, you can disable or remove Windows PowerShell 2.0 (which is an older version) using command-line.
To remove PowerShell 2.0, follow these steps:
1. Press Win + X and choose Windows PowerShell (Admin) to open PowerShell with administrative privileges.
2. Type the following command and press Enter:
“`
Disable-WindowsOptionalFeature -Online -FeatureName MicrosoftWindowsPowerShellV2Root
“`
This will disable the PowerShell 2.0 feature on your system.
If you wish to completely remove PowerShell 2.0 from your system, use the following command:
“`
Uninstall-WindowsFeature -Name PowerShell-V2
“`
Keep in mind that removing an essential component like PowerShell can lead to instability or other issues with your system. It’s not recommended to remove or disable the latest version of PowerShell (Windows PowerShell 5.1 or PowerShell Core 6+).

What are the most efficient methods to remove a PowerShell module from the command-line?
There are two efficient methods to remove a PowerShell module from the command-line:
1. Uninstall-Module: This cmdlet allows you to remove a module that has been installed using the Install-Module cmdlet. To use Uninstall-Module, you must have the PowerShellGet module installed.
Example:
“`
Uninstall-Module -Name
“`
Replace “ with the name of the module you want to remove.
2. Manual Removal: If the module was not installed using Install-Module or you don’t have the PowerShellGet module, you can manually remove the module by deleting its folder from the file system. PowerShell modules are usually stored in one of the following locations:
– `C:UsersDocumentsWindowsPowerShellModules`
– `C:Program FilesWindowsPowerShellModules`
– `C:Windowssystem32WindowsPowerShellv1.0Modules`
Navigate to the appropriate folder and delete the module folder to remove the module.
Remember to close and reopen any active PowerShell sessions after removing the module to refresh the available modules list.
Are there any precautions to take or common issues faced when uninstalling a PowerShell module via the command-line?
Yes, there are certain precautions and common issues that may arise when uninstalling a PowerShell module via the command-line.
1. Administrator Privileges: Ensure you have the necessary permissions to uninstall a module. In many cases, you will need to run PowerShell as an administrator to perform this action.
2. Module Dependencies: Be aware of any dependencies on the module you’re uninstalling. Removing a module could cause other modules or scripts to fail if they rely on the one being removed.
3. Module Version: Verify the version of the module you want to uninstall. Keep in mind that you might have multiple versions of the same module installed on your system. Use the ‘-RequiredVersion’ parameter with the ‘Uninstall-Module’ cmdlet to specify the exact version you want to remove.
4. Error Handling: Always check for errors or warnings during the uninstallation process. The ‘Uninstall-Module’ cmdlet may not always provide sufficient information about the cause of the failure. Make use of the ‘$Error’ variable or the ‘Try-Catch-Finally’ block for better error handling.
5. Profile Scripts: Ensure that any references to the module are removed from your profile scripts. This will prevent errors from occurring when those scripts are executed in future sessions.
6. Reboot Requirement: In some cases, a system reboot may be required to complete the uninstallation process, especially if the module registered system components or services.
In summary, when uninstalling a PowerShell module via the command-line, make sure to have administrator privileges, be aware of module dependencies and versions, handle errors effectively, update your profile scripts, and be prepared for potential reboot requirements.
