In Windows Server 2012 R2 Microsoft finally added in PowerShell support for Windows Deployment Services.
The official TechNet documentation that you find here, is not entirely correct though: The module is not named WindowsDeploymentServices as the TechNet documentation states, but instead WDS.
Note: The cmdlets only works if you execute them locally on the WDS server, adding WDS Tools on another server won't help. To get the WDS cmdlets to work remotely, you can use Invoke-Command with CredSSP. Check Brad Rutkowski's blog for a nice article on configuring CredSSP.
Anyway, to list all available cmdlets, simply run: Get-Command -Module WDS
If you want to count the numbers (out of curiosity), simply add .Count, and put the command inside (), like this:
(Get-Command -Module WDS).Count
Adding boot images
As an example, here is how to add a MDT 2013 boot image to WDS.
Import-WdsBootImage -Path D:\MDTProduction\Boot\LiteTouchPE_x64.wim -NewImageName "MDT Production x64" -SkipVerify
Note: When testing on a clean install of WDS, I had to close and reopen the WDS console for the boot image to appear. Refreshing the Boot Images was not enough.
Prestaging a client
Here is a sample to prestage a machine based on Mac Address:
New-WdsClient -DeviceID "00155D000087" -DeviceName "PC0087" -BootImagePath "Boot\x64\Images\LiteTouchPE_x64.wim"
Controlling PXE policy per device
You can also add the -PxePromptPolicy OptIn option to control the PXE prompt policy.
