The Definitive Guide to PSADT in Intune: Enterprise Packaging at Scale

Published: 2026-07-01 | Category: Learning (ID: 173)

01. Why standard Intune Win32 apps fail at scale

Most admins rely on the standard „Install command“ in the Intune console. While this works for simple .msi files, it falls apart with complex software that requires:

• Custom UI notifications to the end-user.
• Complex pre-installation checks (Registry, Files, Processes).
• Controlled restart behavior that doesn’t kill user productivity.

02. The PSAppDeployToolkit (PSADT) Architecture

PSADT acts as a wrapper. Instead of calling the installer directly, Intune calls Deploy-Application.ps1. This script handles the entire lifecycle of the deployment.

# Logic Flow:
Pre-Installation -> Installation -> Post-Installation
(Checks) -> (Execution) -> (Cleanup/Reboot)

03. Step-by-Step: Wrapping a Legacy App

Files folder.
3. Define the installation logic in the Installation section of Deploy-Application.ps1.
4. Package as .intunewin using the Win32 Content Prep Tool.

04. Deployment Strategy: The Chain

Intune Win32 App -> PSADT Wrapper -> App Installer.
