Adding ADSI Support for WinPE 10

This feels like the never ending story… I created an ADSI plugin for WinPE 2.0 back in 2007/2008-ish, and for every new release of WinPE I get requests for a new version. So here it is.

Note: I understand that you may have existing scripts using the ADSI feature in WinPE that you want to use for Windows 10 deployments, but please start using web services instead. It’s way more secure, has more features, and doesn’t require unsupported hacks like this one.

Disclaimer: Adding ADSI support to WinPE 10 is not supported by Microsoft.

Updated February 20, 2016: Added x86 support as well.


Make sure you have Windows ADK 10 installed, then the download the ADSI Plugin for WinPE 10.

Step-by-step guide

In this example you add support for ADSI to WinPE 10 x64, but you also find files for the x86 version in the download.

1. Extract the ADSI Plugin to C:\Plugins.

2. Copy the following files from a Windows 10 x64 image/installation to C:\Plugins\ADSIx64.


3. From an elevated PowerShell prompt, run the CreateBootImage_x64.ps1 script

    Throw "Failed to generate ISO with exitcode: $($Proc.ExitCode)"

4. Boot a VM on the WinPE10_x64_ADSI.iso, or add the WIM to your deployment solution. Once booted, run the Connect_to_DC_Sample.vbs script to verify ADSI works (modify server/domain name if needed first).
