ConfigMgr New PC TS Unattend.xml

You can deploy OSConfig in a Configuration Manager Task Sequence in the Specialize Phase of an Unattend.xml. The following requirements must be met

Create a new Package with Source Files to the root of your OSConfig content. Do not create a Program. Distribute Content to your Distribution Points

Edit your Partition Disk steps to ensure that the Windows Partition Drive Letter is assigned a Variable. This is typically OSDisk. Repeat this process for both BIOS and UEFI Windows Partitions

Inset a Run Command Line step with your OSConfig Package to copy the contents locally. Use the following Command Line

cmd.exe /c md %OSDisk%\ProgramData\OSConfig & cmd.exe /c xcopy ".\*" %OSDisk%\ProgramData\OSConfig /y /e

OSConfig is executed by adding the following command line to the Specialize Phase in the Unattend.xml

PowerShell.exe -ExecutionPolicy Bypass -File C:\ProgramData\OSConfig\OSConfig.ps1

Here is a minimal Unattend.xml (x64 and x86) for reference that can be used. Create a Package for your Unattend.xml

Make sure the Apply Operating System step contains the proper Unattend.xml and the OSDisk settings

During OS Deployment you will see progress during the Specialize phase before first logon

If everything worked fine, your Operating System should show your customizations immediately.
