📘 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

1. App Package
2. Deployment Configuration
3. Detection Logic
4. Assignment
5. Execution on Endpoint
6. 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

1. Package app using IntuneWinAppUtil
2. Upload .intunewin
3. Configure:
   • Install command
   • Uninstall command
   • Detection rules
4. Define requirements
5. 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

---
