📘 Application Management with Microsoft Intune

1️⃣ Introduction to Application Management in Intune (Detailed)

Application Management in Intune is the process of packaging, deploying, managing, updating, and troubleshooting applications across managed devices.

Why Application Management Is Critical

In modern enterprises:

Users work remotely
Devices are cloud-managed
Manual installs are not scalable
Security must be enforced automatically

Intune solves this by providing:

Centralized control
Policy-based deployment
User-based or device-based installs
Integration with security and identity (Entra ID)

Core Capabilities

Application deployment
App updates & replacement
Conditional access for apps
App protection (MAM)
Reporting and troubleshooting

2️⃣ Structure of Application Management in Intune

High-Level Architecture

Admin → Intune Portal → Policy + App Config
      → Entra ID Groups
      → Device / User
      → Intune Management Extension (IME)

Logical Components

App Package
Deployment Configuration
Detection Logic
Assignment
Execution on Endpoint
Monitoring & Reporting

3️⃣ Overview of Applications and Types in Intune

Windows Application Types Explained

App Type	Description	Typical Usage
Win32 App	Traditional EXE/MSI apps	Enterprise apps
Microsoft Store (New)	Winget-backed Store apps	Common utilities
MSIX	Modern packaged apps	Clean installs
LOB (MSI)	Simple MSI apps	Legacy installs
Web App	URL-based apps	SaaS platforms
Microsoft 365 Apps	Office apps	Productivity
Microsoft Edge	Browser	Standardization

4️⃣ Assignment Options for Applications (Deep Explanation)

Assignment Behavior

Option	What Happens
Required	App installs automatically
Available	User installs from Company Portal
Uninstall	App removed if detected

Assignment Targeting

User groups → follows user across devices
Device groups → fixed hardware targeting
Filters → OS version, device ownership, SKU

Best Practices

✔ Use Required for security tools
✔ Use Available for optional apps
✔ Use Filters to reduce group sprawl

5️⃣ Creating & Deploying Windows Applications (Step-by-Step)

🔹 A. Win32 Applications (Most Important)

What Is a Win32 App?

A Win32 app is any traditional Windows installer:

.exe
.msi
Scripts or custom installers

Step-by-Step Deployment

Package app using IntuneWinAppUtil
Upload .intunewin
Configure:
- Install command
- Uninstall command
- Detection rules
Define requirements
Assign app

Detection Rule (Critical Concept)

Intune must detect the app to mark install as successful.

Detection methods:

File existence
Registry key/value
MSI product code
Custom script

⚠️ Wrong detection = endless reinstall loop

🔹 B. Microsoft Store Apps (New Experience)

Key Characteristics

Uses Windows Package Manager (Winget)
No packaging required
Auto updates supported
Cleaner than legacy Store apps

Limitations

Limited customization
Dependent on Microsoft Store availability

🔹 C. MSIX Applications

What Is MSIX?

MSIX is a modern Windows app packaging format that:

Is containerized
Has clean install/uninstall
Supports version upgrades

Advantages

✔ No registry pollution
✔ Built-in detection
✔ Safe rollback

Disadvantages

❌ App compatibility issues
❌ Packaging complexity

6️⃣ Deep Dive Troubleshooting (Windows Applications)

Key Log Locations

C:\ProgramData\Microsoft\IntuneManagementExtension\Logs

Log File	Purpose
IntuneManagementExtension.log	Core engine
AppWorkload.log	App execution
Detection.log	Detection logic
AgentExecutor.log	Script execution

Common Issues & Fixes

Issue	Root Cause	Resolution
App stuck installing	Detection fails	Fix detection rule
Error 0x80070001	Installer failed	Test locally
Reinstall loop	Wrong detection	Use registry/file
App not visible	Assignment issue	Check group

7️⃣ Other Application Types

Web Apps

Simple URL shortcuts
Can be pinned
Used for cloud platforms

Mobile Apps

iOS / Android managed apps
Works with:
- App Protection Policies
- Conditional Access
- BYOD scenarios

8️⃣ Microsoft 365 Apps and Microsoft Edge

Microsoft 365 Apps

Custom install
App-level selection
Channel control
Shared device licensing

Microsoft Edge

Automatic deployment
Extension enforcement
Security baseline integration

9️⃣ ⭐ Comparison Table: Win32 vs Store vs MSIX

🔍 Detailed Comparison

Feature	Win32 App	Microsoft Store (New)	MSIX App
Packaging Required	✅ Yes	❌ No	✅ Yes
Installer Types	EXE / MSI	Store / Winget	MSIX
Detection Rules	Manual	Automatic	Built-in
Custom Install Cmd	✅ Yes	❌ No	❌ Limited
Uninstall Control	✅ Full	⚠️ Limited	✅ Clean
Supersedence	✅ Yes	❌ No	✅ Versioned
Updates	Manual	Automatic	Automatic
App Isolation	❌ No	✅ Yes	✅ Yes
Enterprise Flexibility	⭐⭐⭐⭐⭐	⭐⭐⭐	⭐⭐⭐⭐
Recommended Use	Complex apps	Common tools	Modern apps

✅ When to Use What

Win32 → Complex enterprise software
Store (New) → Standard utilities
MSIX → Modern, clean apps

🔚 Final Summary

✔ Win32 apps give maximum control
✔ Store apps offer simplicity & auto-updates
✔ MSIX provides modern, clean deployment
✔ Detection rules decide success or failure
✔ Logs are mandatory for troubleshooting

If you want next steps, I can:

Convert this into a PDF / Word document
Create hands-on lab exercises
Add real interview questions
Make flowcharts for troubleshooting
Create a Win32 packaging checklist

Just tell me 👍

Perfect choice 👌

Below are clear, exam-ready troubleshooting flowcharts plus a practical Win32 packaging checklist that real Intune admins actually use in production.

I’ve written this so you can:

Follow it during a live issue

Memorize it for interviews

Use it as a build standard
