DSC Resource Kit Release March 2017

We just released the DSC Resource Kit!

This release includes updates to 10 DSC resource modules
, including 19 new DSC resources
. In these past 6 weeks, 155 pull requests (the most ever!)
have been merged and 71 issues
have been closed, all thanks to our amazing community!

A few weeks ago we also released a new DSC resource module called SecurityPolicyDsc with resources to configure local security policies through secedit. Thank you to Jason Walker for this great new module!

The modules updated in this release are:

  • OfficeOnlineServerDsc
  • PSDscResources
  • SecurityPolicyDsc
  • SharePointDsc
  • xCertificate
  • xExchange
  • xPSDesiredStateConfiguration
  • xRemoteDesktopSessionHost
  • xSQLServer
  • xWindowsUpdate

For a detailed list of the resource modules and fixes in this release, see the Included in this Release section below.

Our last community call
for the DSC Resource Kit was last week on March 1. A recording
of our updates as well as summarizing notes
are available. Join us next time at 9AM PST on April 12 to ask questions and give feedback about your experience with the DSC Resource Kit. Keep an eye on the community agenda
for the link to the call.

We strongly encourage you to update to the newest version of all modules using the PowerShell Gallery, and don’t forget to give us your feedback in the comments below, on GitHub, or on Twitter ( @PowerShell_Team

All resources with the ‘x’ prefix in their names are still experimental – this means that those resources are provided AS IS and are not supported through any Microsoft support program or service. If you find a problem with a resource, please file an issue
on GitHub.

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 inWMF 5.0) to find modules with DSC Resources:

# To list all modules that are part of the DSC Resource Kit
Find-Module -Tag DSCResourceKit 
# To list all DSC resources from all sources 

To find a specific
module, go directly to its URL on the PowerShell Gallery:


For example:


How to Install DSC Resource Modules From the PowerShell Gallery

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

Install-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:

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