.DESCRIPTION 

A simple PowerShell-based tool for analyzing Intune Management Extension logs and diagnostics.

Quickly troubleshoot Intune issues with an intuitive UI and built-in ZIP extraction.

This script provides a simple UI to analyze Intune Management Extension logs.

- Drag & Drop a folder or ZIP file

- Click "Analyze"

- The script will run the diagnostics script on the selected logs

All Kudos for the logic behind the diagnostics script go to the original author: 

- Petri Paavola
