This project serves as a set of "wrapper" commands that utilize the Lability module which is a terrific tool for creating a lab environment of Windows-based systems. The downside is that it is a difficult module for less experienced PowerShell users. The configurations and control commands for the Hyper-V virtual machines in this module are written in PowerShell using Desired State Configuration (DSC) and deployed via Lability commands. If you feel sufficiently skilled, you can skip using this project and use the Lability module on your own. Note that the Lability module is not owned or managed by Pluralsight. This project and all files are released under an MIT License - meaning you can copy and use as your own, modify, borrow, steal - whatever you want.

While this project is under the Pluralsight banner, it is offered AS-IS as a free tool with no official support from Pluralsight. Pluralsight makes no guarantees or warranties. This project is intended to be used for educational purposes only.

Beginning with module version 4.17.0, you can run Open-PSAutoLabHelp to view a local PDF version of the module's documentation.


This module is designed and intended to be run on a Windows 10/11 client that supports virtualization. Windows 10 Pro or Enterprise and later should be sufficient. It is assumed you will be installing this on a Windows 10/11 desktop running Windows PowerShell 5.1. This module will not work and is unsupported on any Home or Student edition, although there are reports of the module working on Windows 10 Education. The module might run on Windows Server (2016 or 2019) platforms, but this capability has not been fully tested nor is it supported.

Using this in a nested virtual environment may work, but don't be surprised if there are problems, especially related to networking and NAT.

The host computer, where you are installing, must meet the following requirements:

  • Windows PowerShell 5.1.
  • A high-speed internet connection.
  • Minimum 16GB of RAM (32GB is recommended).
  • Minimum 100GB free disk space preferably on a fast SSD device or equivalent.
  • An Intel i5 processor or equivalent. An i7 is recommended for the best performance.
  • Windows PowerShell Remoting enabled.
  • You should be logged in with a local or domain user account. The setup process may not work properly if using an O365 or Microsoft account to logon to Windows.

You must have administrator access and be able to update the TrustedHosts setting for PowerShell remoting. If you are in a corporate environment, these settings may be locked down or restricted. If this applies to you, this module may not work properly, if at all.

This module and configurations have NOT been tested running from PowerShell Core or PowerShell 7 and is not supported at this time.

Pester Requirement

The module uses a standard PowerShell tool called Pester to validate lab configurations. Without getting into technical details, if you are running the out-of-the-box version of Pester on Windows 10, you need to manually update Pester before attempting to install this module. In an elevated Windows PowerShell session run this command:

Get-Module Pester -ListAvailable

If the only result you get is for version 3.4.0, then you must run:

Install-Module Pester -RequiredVersion 4.10.1 -Force -SkipPublisherCheck

Re-run the Get-Module to verify version 4.10.1 is installed. If you have newer versions installed, that will have no effect on this module. Once you have verified Pester version 4.10.1 you can install the PSAutoLab module.


This module has been published to the PowerShell Gallery. It is recommended that you have at least version 2.2 of the PowerShellGet module which handles module installations.

Open an elevated PowerShell prompt and run:

Install-Module PSAutoLab -Force -SkipPublisherCheck

The installation should install required dependencies which is why you need the additional parameters.

If prompted, answer yes to update the nuget version and to install from an untrusted repository, unless you've already marked the PSGallery as trusted. If you have an old copy of this module from before Pluralsight took ownership, you will get an error. Manually remove the old module files and try again.

Do not download or use any of the release packages from this Github repository. You must install this module from the PowerShell Gallery.

See the Changelog for update details.

DO NOT run this module on any mission-critical or production system.

If you encounter issues with a basic installation and setup, you should read and use the detailed setup instructions.

You can verify the module with these commands:

PS C:\> Import-Module PSAutoLab -force
PS C:\> Get-Module PSAutoLab

ModuleType Version    Name           ExportedCommands
---------- -------    ----           ----------------
Script     4.18.0      PSAutoLab     {Enable-Internet, Get-LabSnapshot,...}

Your version number may differ.


This module and its configurations should not conflict with any existing Hyper-V virtual machines or networking. But you should be aware that the module will create a new., internal Hyper-V switch called LabNet. This switch will use a NAT configuration called LabNat.

PS C:\> Get-NetNat LabNat

Name                             : LabNat
ExternalIPInterfaceAddressPrefix :
InternalIPInterfaceAddressPrefix :
IcmpQueryTimeout                 : 30
TcpEstablishedConnectionTimeout  : 1800
TcpTransientConnectionTimeout    : 120
TcpFilteringBehavior             : AddressDependentFiltering
UdpFilteringBehavior             : AddressDependentFiltering
UdpIdleSessionTimeout            : 120
UdpInboundRefresh                : False
Store                            : Local
Active                           : True

The file in each configuration folder should provide an indication of what VMs will be created. You can also check the VMConfigurationData.psd1 file.

PS C:\Autolab\Configurations\MultiRole\> (Import-PowerShellDataFile .\VMConfigurationData.psd1).allnodes.Nodename

Current configurations will use these names for the virtual machine and computer name:

  • DC1
  • S1
  • S2
  • Cli1
  • Cli2
  • PullServer
  • DOM1
  • SRV1
  • SRV2
  • SRV3
  • WIN10
  • WIN11
  • Win10Ent
  • S12R2
  • S12R2GUI

Nano Server images have been removed from configurations. These configurations were using the now deprecated version of Nano. Microsoft has changed direction with regards to Nano Server and none of the existing configurations use this new version.

Previous Versions

If you installed previous versions of this module (v3.x) and struggled, hopefully, this version will be an improvement. To avoid any other complications, it is STRONGLY recommended that you manually remove the old version which is most likely under C:\Program Files\WindowsPowerShell\Modules\PSAutoLab. You can run a command like:

Get-Module PSAutoLab -ListAvailable | Select-Object Path

To identify the module location. Use this information to delete the PSAutoLab folder.

The previous version was not installed using PowerShell's module cmdlets so it can't be updated or removed except manually.

Note for VMware Users

This project is designed to work with Hyper-V. If you are going to build a Host VM of Server 2016 or Windows 10, In the general settings for your VM, you must change the OS type to Hyper-V(Unsupported) or the Host Hyper-V will not work! This module and its configurations have not been tested for compatibility with VMware.

Aliases and Language

While this module follows proper naming conventions, the commands you will typically use employ aliases that use non-standard verbs such as Run-Lab. This is to avoid conflicts with commands in the Lability module and to maintain backward compatibility. You can use the aliases or the full function name. All references in this document use the aliases. You do not need to run any commands from the Lability module.

Setup Host

The first time you use this module, you will need to configure the local machine or host. Open an elevated PowerShell session and run:


This will install and configure the Lability module and install the Hyper-V feature if it is missing. By default, all AutoLab files will be stored under C:\AutoLab, which the setup process will create. If you prefer to use a different drive, you can specify it during setup.

Setup-Host -DestinationPath D:\AutoLab

You will be prompted to reboot, which you should do especially if the setup had to add the Hyper-V feature. To verify your configuration open an elevated PowerShell session and run this command:

PS C:\> Get-PSAutoLabSetting

AutoLab                     : C:\Autolab
PSVersion                   : 5.1.19041.1

PowerShellGet               : 2.2.3
PSDesiredStateConfiguration : 1.1

Some of your values may be different. Please include this information when reporting any problems or issues.

Lab Summary

Once the host setup is complete, you can use the module's Get-LabSummary command to better understand what the lab configuration will setup. Run the command in the configuration folder.

PS C:\Autolab\Configurations\SingleServer-GUI-2016\> Get-LabSummary

   Computername: S1 VMName: S1

Lab                       IPAddress       MemGB Procs Role    Description
---                       ---------       ----- ----- ----    -----------
SingleServer-GUI-2016        4     1 RDP     Windows Server
                                                              2016 Standard
                                                              64bit English

The module includes a custom format file. You might also run the command like this:

PS C:\Autolab\Configurations\SingleServer-GUI-2016> Get-LabSummary |
Select-Object *

Computername : S1
VMName       : S1
InstallMedia : 2016_x64_Standard_EN_Eval
Description  : Windows Server 2016 Standard 64bit English Evaluation
Role         : RDP
IPAddress    :
MemoryGB     : 4
Processors   : 1
Lab          : SingleServer-GUI-2016

The Computername and VMName properties might differ if you are using an environmental prefix. The Computername is how the virtual machines refer to each themselves and each other. The VMName is how you reference them in Hyper-V.

Creating a Lab

Lab information is stored under the AutoLab Configurations folder, which is C:\AutoLab\Configurations by default. Open an elevated PowerShell prompt and change location to the desired configuration folder. View the and/or files in the folder to learn more about the configuration. Where possible information about what course goes with a particular Pluralsight course will be indicated.

A Note on Pluralsight Labs

This module started several years ago and there are several Pluralsight courses that rely on configurations that may no longer exist. Configurations that were named as Test or POC were not assumed to be used in any courses. But that is turning out to not be the case. If you are trying to setup a lab for a specific course, and can't find the configuration the instructor calls for, please post an issue indicating the configuration you are looking for and the title of the Pluralsight course. Hopefully, there is an existing configuration you can use. Or the module can be updated with an appropriate lab configuration. In some cases, the course may assume a different password. All configurations use P@ssw0rd for all passwords.

The first time you set up a lab, Lability will download evaluation versions of required operating systems in ISO format. This may take some time depending on your Internet connection. These downloads only happen when the required ISO is not found locally. When you wipe and rebuild a lab it won't download files a second time.

Once the lab is created, you can use the PSAutoLab commands for managing it. If you have additional PowerShell experience, you can manage individual virtual machines using the Hyper-V manager or cmdlets.

It is assumed that you will only have one lab configuration created at a time.

Please be aware that all configurations were created for an EN-US culture and keyboard.

Manual Setup

Most, if not all, configurations should follow the same manual process. Run each command after the previous one has completed.

To verify that all virtual machines are properly configured you can run Validate-Lab. This will invoke a set of tests and keep looping until everything passes. Due to the nature of DSC and the complexity of some configurations, this could take up to 60 minutes. You can use Ctrl+C to break out of the testing loop at any time. You can manually run the test one time to see the current state of the configuration.

PS C:\Autolab\Configurations\SingleServer\> Invoke-Pester VMValidate.test.ps1

This can be useful for troubleshooting.

Unattended Setup

As an alternative, you can setup a lab environment with minimal prompting.

PS C:\Autolab\Configurations\SingleServer\> Unattend-Lab

Assuming you don't need to install a newer version of nuget, you can leave the setup alone. It will run all of the manual steps for you. Beginning in version 4.3.0 you also have the option to run the unattend process in a PowerShell background job.

PS C:\Autolab\Configurations\SingleServer\> Unattend-Lab -asjob

Use the PowerShell job cmdlets to manage.

Stopping a Lab

To stop the lab VMs, change to the configuration folder in an elevated Windows PowerShell session and run:

PS C:\Autolab\Configurations\SingleServer\> Shutdown-Lab

You can also use the Hyper-V manager or cmdlets to manually shut down virtual machines. If your lab contains a domain controller such as DOM1 or DC1, that should be the last virtual machine to shut down.

Starting a Lab

The setup process will leave the virtual machines running. If you have stopped the lab and need to start it, change to the configuration folder in an elevated Windows PowerShell session and run:

PS C:\Autolab\Configurations\SingleServer\> Run-Lab

You can also use the Hyper-V manager or cmdlets to manually start virtual machines. If your lab contains a domain controller such as DOM1 or DC1, that should be the first virtual machine to start up.

Lab Checkpoints

You can snapshot the entire lab very easily. Change to the configuration folder in an elevated Windows PowerShell session and run:

PS C:\Autolab\Configurations\SingleServer\> Snapshot-Lab

To quickly rebuild the labs from the checkpoint, run:

PS C:\Autolab\Configurations\SingleServer\> Refresh-Lab

Or you can use the Hyper-V cmdlets to create and manage VM snapshots.

To Remove a Lab

To destroy the lab completely, change to the configuration folder in an elevated Windows PowerShell session and run:

PS C:\Autolab\Configurations\SingleServer\> Wipe-Lab

This will remove the virtual machines and DSC configuration files. If you intend to rebuild the lab or another configuration, you can keep the LabNat virtual switch. This is the default behavior. If you want to remove everything you would need to run a command like this:

PS C:\Autolab\Configurations\SingleServer\> Wipe-Lab -force -removeswitch

Customizing a Lab

It is possible to customize a lab configuration by editing the VMConfigurationData.psd1 file that is in each configuration folder. You must modify the file before creating the lab. For example, the configuration my use Server Core and you want the Desktop Experience on the server. Open the file in your scripting editor and scroll down to find the Node definitions.

    NodeName                = 'DOM1'
    IPAddress               = ''
    Role                    = @('DC', 'DHCP', 'ADCS')
    Lability_BootOrder      = 10
    Lability_BootDelay      = 60
    Lability_timeZone       = 'US Mountain Standard Time'
    Lability_Media          = '2016_x64_Standard_Core_EN_Eval'
    Lability_MinimumMemory  = 2GB
    Lability_ProcessorCount = 2
    CustomBootStrap         = @'
            # This must be set to handle larger .mof files
            Set-Item -path wsman:\localhost\maxenvelopesize -value 1000

    NodeName           = 'SRV1'
    IPAddress          = ''
    Role               = @('DomainJoin')
    Lability_BootOrder = 20
    Lability_timeZone  = 'US Mountain Standard Time'
    Lability_Media     = '2016_x64_Standard_Core_EN_Eval'

You can edit the Lability_Media setting. Change the setting using one of these ID values from running Get-LabMedia.

You can also make changes to values such as minimum memory and processor count. When you run Unattend-Lab or Setup-Lab you can use the -UseLocalTimeZone to set all virtual machines to use your time zone. You could make minor changes to the IP address such as changing the address from to To change the entire subnet will require modifying the virtual switch and should not be attempted unless you are very proficient with PowerShell and Hyper-V.

Note that if you make changes, the validation test may fail unless you modify it. But you can always try to run the lab without validating it.

If you make a mistake or want to restore the original configurations, run the Refresh-Host command.

Windows 10 Remote Server Administration Tools (RSAT)

A number of lab configurations that include a Windows 10 client will also install RSAT. In the past, this has meant trying to install all RSAT features. This takes a long time and has caused validation issues. Beginning with v4.21.0 of the PSAutlab module, the RSAT configuration and testing will only use a subset of features.

  • ActiveDirectory
  • BitLocker +*CertificateServices
  • DHCP
  • Dns
  • FailoverCluster
  • FileServices
  • GroupPolicy
  • IPAM.Client
  • ServerManager

If you require any other tool, you will need to use Add-WindowsCapability in the Windows 10/11 client to add it.

This change has improved setup-performance and module stability.

Windows Updates

When you build a lab, you are creating Windows virtual machines based on evaluation software. You might still want to make sure the virtual machines are up to date with security patches and updates. You can use Update-Lab to invoke Windows update on all lab members. This can be a time-consuming process, so you have an option to run the updates as a background job. Just be sure not to close your PowerShell session before the jobs complete.

PS C:\Autolab\Configurations\PowerShellLab\> update-lab -AsJob

Id   Name        PSJobTypeName   State      HasMoreData   Location    Command

WARNING: SRV3 requires a reboot

Run the update process as a background job. Use the PowerShell job cmdlets to manage.

Updating PSAutoLab

As this module is updated over time, new configurations may be added, or bugs fixed in existing configurations. There may also be new Lability updates. Use PowerShell to check for new versions:

Find-Module PSAutoLab

And update:

Update-Module PSAutoLab -Force

If you update, it is recommended that you update the AutoLab configuration.


This will update the Lability and Pester modules if required and copy all-new configuration files to your AutoLab\Configurations folder. It will NOT delete any files.

Removing PSAutoLab

If you want to completely remove the PSAutoLab module, first use Wipe-Lab to remove any existing lab configurations including the Hyper-V switch. Run this command to uninstall the module and its dependencies

Uninstall-Module PSAutoLab,Lability

You may need to manually delete the C:\Autolab folder. If you want to remove the NAT configuration"

Remove-NetNat LabNat

If you want to remove Hyper-V you can use the Control Panel to manually remove the optional feature. Or you can try using PowerShell.

Get-WindowsOptionalFeature -FeatureName *Hyper* -online |
Disable-WindowsOptionalFeature -Online

You will almost certainly need to reboot to complete the removal process.


If you are running Pester v5.x you need to be running at least version 4.11.0 of this module.

The validation tests for each configuration are written for the Pester module. This is a widely adopted testing tool. In June of 2020 version 5 was released. This version of Pester introduced several breaking changes to how tests are written. The tests in this module are incompatible with Pester 5.0 and will need to be re-written. As an interim step, this module will test for Pester v 4.10.1. If you don't have that version it will be installed when you run Setup-Host. Or if you've already setup Autolab you can run Refresh-Host. If you have Pester 5.x, it will not be uninstalled, but it will be removed from the current PowerShell session.


Package Provider or Module Installation

If you try to install a module or update the nuget provider, you might see warnings like these:

WARNING: Unable to download from URI '' to ''.
WARNING: Unable to download the list of available providers. Check your internet connection.
PackageManagement\Install-PackageProvider : No match was found for the specified search criteria for the provider 'NuGet'. The package provider requires 'PackageManagement' and
'Provider' tags.

The first thing to check is to make sure you are using valid TLS settings. You can try running this command in PowerShell:

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

Beginning with v4.17.0 of this module, this change is made when the module is imported. It will only last for as long as your PowerShell session is running.

You could also modify the registry in an elevated PowerShell session for a more permanent solution.

Set-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value 1

Modifying the registry will require a reboot for the changes to take effect.

If the problem is the nuget provider, after making the TLS changes try:

Install-PackageProvider nuget -force -forcebootstrap

You might also need to update the PackageManagement and/or PowerShellGet modules.

Update-Module powershellget,packagemanagement -force

Autolab Configurations

The commands and configurations in this module are not foolproof. During testing a lab configuration will run quickly and without error on one Windows 10 desktop but fail or take much longer on a different Windows 10 desktop. Most setups should be complete in under an hour. If validation is failing, manually run the validation test in the configuration folder.

PS C:\Autolab\Configurations\SingleServer\> Invoke-Pester VMValidate.test.ps1

Take note of which virtual machines are generating errors. Verify the virtual machine is running in Hyper-V. On occasion for reasons still undetermined, sometimes a virtual machine will shutdown and not reboot. This often happens with the client nodes of the lab configuration. Verify that all virtual machines are running and manually start those that have stopped using the Hyper-V manager or cmdlets.

Sometimes even if the virtual machine is running, manually shutting it down and restarting it can resolve the problem. Remember to wait at least 5 minutes before manually running the validation test again when restarting any virtual machine.

As a last resort, manually break out of any testing loop, wipe the lab and start all-over.

If you still are having problems, wipe the lab and try a different configuration. This will help determine if the problem is with the configuration or a larger compatibility problem.

At this point, you can open an issue in this repository. Open an elevated PowerShell prompt and run Get-PSAutoLabSetting which will provide useful information. Copy and paste the results into a new issue along with any error messages you are seeing.

Known Issues

I get an error when importing the module

Starting with version 4.12.0 of this module, you might see this error when you import the module.

Import-Module : Assertion operator name 'Be' has been added multiple times.

This is most likely due to a conflict in Pester versions. The solution is to remove the Pester module from your current session.

Get-Module Pester | Remove-Module

Then import this module again.

I get an error trying to update Lability

If you try to run Refresh-Host you might see an error about a certificate mismatch. Between v0.18.0 and v0.19.0 the Lability module changed code signing certificates. If you encounter this problem, run

Refresh-Host -SkipPublisherCheck

Multiple DSC Resources

Due to what is probably a bug in the current implementation of Desired State Configuration in Windows, if you have multiple versions of the same resource, a previous version might be used instead of the required one. You might especially see this with the xNetworking module and the xIPAddress resource. If you have any version older than you might encounter problems. Run this command to see what you have installed:

Get-DSCResource xIPAddress

If you have older versions of the module, uninstall them if you can.

Uninstall-Module xNetworking -RequiredVersion

Beginning with version 4.20.0, you might see the same type of errors with the xDHCP resource. If you encounter errors like Invalid MOF definition for node 'DC1': Exception calling "ValidateInstanceText" with "1" argument(s): "Undefined property IsSingleInstance you might have an older version of a DSCResource module installed.

Run Get-Module xdhcpserver -list and remove anything older than version 3.0.0.

Uninstall-Module xdhcpserver -RequiredVersion

It is recommended that you restart your PowerShell session and try the lab setup again.


This module is a continuation of the work done by Jason Helmick and Melissa (Missy) Januszko, whose efforts are greatly appreciated. Beginning with v4.0.0, this module is unrelated to any projects Jason or Missy may be developing under similar names.

We also appreciate all of the work that has gone into the Lability module. The Lability and PSAutoLab modules are completely separate and independently maintained.

Road Map

These are some of the items that are being considered for future updates:

  • While Lability currently is for Windows only, it would be nice to deploy a Linux VM.
  • Offer an easy way to customize a lab configuration such as node names and operating systems.

A complete list of enhancements (and bugs) can be found in the Issues section of this module's GitHub repository. Feel free to make a suggestion.
