For those utilizing Intune for device management, being able to deliver software much like pre-Intune systems is a must. For Windows, Intune supports both Microsoft Store apps and legacy, “classic” apps. To deliver classic apps, a tool is available that converts (or wrap) the packages into the .intunewin format.
The tool is available from here: Microsoft Win32 Content Prep Tool
Use the Microsoft Win32 Content Prep Tool to pre-process Windows Classic apps. The packaging tool converts application installation files into the .intunewin format. The packaging tool also detects the parameters required by Intune to determine the application installation state. After you use this tool on your apps, you will be able to upload and assign the apps in the Microsoft Intune console.
