IntuneWinAppUtil GUI

PowerShell module with a WPF front‑end that wraps Microsoft’s IntuneWinAppUtil.exe, making it quicker to package Win32 apps for Intune. Includes validation, auto-download of the prep tool, path-length checks, and configuration persistence.

  • Auto-download and cache of the latest IntuneWinAppUtil.exe from Microsoft’s GitHub release.
  • Remembers tool path in %APPDATA%\IntuneWinAppUtilGUI\config.json; optional update-check banner.
  • Detects PSAppDeployToolkit usage and proposes installer/output names; sanitizes invalid filename characters.
  • Path-length indicators plus final MAX_PATH validation at run time.
  • Optional flags: -ShowVersion to display installed/latest module versions, -ForceUpdateBanner for testing.
