You need to prepare a Win32 application file named App1.exe for deployment with Microsoft Intune. What is the first step you should perform?

To deploy a Win32 application like App1.exe via Microsoft Intune, it must first be packaged into the .intunewin format. This format is a compressed and encrypted package that Intune understands and can distribute. The Microsoft Win32 Content Prep Tool is used for this conversion, bundling all necessary installation files and detecting parameters for installation and uninstallation. Creating an app configuration policy or a deployment configuration are subsequent steps after the application is prepared. Uploading to Azure Blob Storage is not a standard or required step for Intune Win32 app deployment; Intune handles storage internally once the .intunewin file is uploaded.
