Win32ContentPrepToolGUI

Win32ContentPrepToolGUI is an open source wrapper for the Win32 Content Prep Tool by Microsoft.

You must download the IntuneWinAppUtil.exe executable from the official Microsoft repo before running this application. This is simply a wrapper and requires the executable to pack your apps to .intunewin format.

Written in Visual Basic .NET, Win32ContentPrepToolGUI is a Windows Forms Application. This simplifies the process of selecting parameters for the prep tool.

How to use

Go to the Releases tab and download the latest version of WIn32ContentPrepToolGUI.exe (Microsoft Defender or Smart Screen will flag this app, this is expected. Just tell Smart Screen or Defender to keep the app).

Download the official Win32 Content Prep Tool (IntuneWinAppUtil.exe) from Microsoft's official repo.

Steps here are written in order of top to bottom (from the top of the GUI to the bottom)

1. Press the Select File button and select the IntuneWinAppUtil.exe.
2. Press the Select File button and select the setup file (This is usually a setup.msi or setup.exe).
3. Press the Select Folder button and select the setup folder (All files in this folder will be packaged into the .intunewin format.
4. Press the Select Folder button and select the output folder (This is where the .intunewin will be saved).
5. The Select catalog folder TextBox and its respective Select Folder Button will be disabled until you specify yes or no using the CatalogFolder CheckBox. If the CheckBox is Checked (True) then the TextBox and Button will be enabled and you must choose a catalog foler to continue.
6. (OPTIONAL) - Choose whether or not you want to use Quiet Mode when generating your .intunewin file. By default, this is disabled.
7. Press the Generate button
8. Celebrate, because you can now upload your .intunewin file to Intune, and you didn't have to type in those long file paths to do it.

Autofill IntuneWinAppUtil.exe

To tell this app where IntuneWinAppUtil.exe is stored, you can use the registry editor. Go to the following key: HKEY_CURRENT_USER\SOFTWARE\WIN32_CONTENT_PREP_TOOL_GUI_CONFIG.

Inside that key is a value called IntuneWinAppUtil_Location. The default value is set to C:\IWAU\IntuneWinAppUtil.exe. Change this to whatever value you want. If the app finds the util tool at that location, it will autofill the value every time you run the GUI.

Here are some valid example values for IntuneWinAppUtil_Location:

1. C:\Intune Utils\Microsoft\IntuneWinAppUtil.exe
2. C:\Users\username\Documents\IntuneWinAppUtil.exe
3. C:\Tools\Intune Tools\Microsoft Win32 Content Prep Tool\IntuneWinAppUtil.exe
