How to Find Released DSC Resource Modules

To see a list of all released DSC Resource Kit modules, go to the PowerShell Gallery and display all modules tagged as DSCResourceKit. You can also enter a module’s name in the search box in the upper right corner of the PowerShell Gallery to find a specific module.

Of course, you can also always use PowerShellGet (available starting in WMF 5.0) to find modules with DSC Resources:

# To list all modules that tagged as DSCResourceKit
Find-Module -Tag DSCResourceKit 
# To list all DSC resources from all sources 

Please note only those modules released by the PowerShell Team are currently considered part of the ‘DSC Resource Kit’ regardless of the presence of the ‘DSC Resource Kit’ tag in the PowerShell Gallery.

To find a specific module, go directly to its URL on the PowerShell Gallery: http://www.powershellgallery.com/packages/< module name > For example: http://www.powershellgallery.com/packages/xWebAdministration

How to Install DSC Resource Modules From the PowerShell Gallery

We recommend that you use PowerShellGet to install DSC resource modules:

Install-Module -Name < module name >

For example:

Install-Module -Name xWebAdministration

To update all previously installed modules at once, open an elevated PowerShell prompt and use this command:


After installing modules, you can discover all DSC resources available to your local system with this command:


How to Find DSC Resource Modules on GitHub

All resource modules in the DSC Resource Kit are available open-source on GitHub. You can see the most recent state of a resource module by visiting its GitHub page at: https://github.com/PowerShell/< module name > For example, for the CertificateDsc module, go to: https://github.com/PowerShell/CertificateDsc.

All DSC modules are also listed as submodules of the DscResources repository in the DscResources folder and the xDscResources folder.
