In this article, we will explore the usage of omadmclient.exe in the Windows 11 environment. Understanding how to utilize this tool is essential for system administrators and engineers who work with mobile device management (MDM) solutions. Although omadmclient.exe is not natively available in Windows 11, we will discuss alternative methods to achieve similar functionality using PowerShell.

omadmclient.exe is a command-line tool used to manage mobile devices through the Open Mobile Alliance Device Management (OMA DM) protocol. It allows administrators to perform various tasks such as querying device information, applying configuration settings, and initiating device actions remotely. While the tool was originally designed for Windows Mobile and Windows Phone devices, it can still be used in certain scenarios with Windows 10. However, it is not officially supported in Windows 11.

Examples:

1. Querying Device Information: To retrieve device information using PowerShell in Windows 11, you can use the following command:

   Get-CimInstance -Namespace "root\cimv2\mdm\dmmap" -ClassName "MDM_DeviceInfo" | Select-Object -Property *

   This command will provide you with various details about the device, including the manufacturer, model, operating system version, and more.

2. Applying Configuration Settings: To apply configuration settings to a device using PowerShell in Windows 11, you can utilize the Set-CimInstance cmdlet. For example, to set a custom wallpaper on a device, you can use the following command:

   $wallpaperPath = "C:\Path\to\wallpaper.jpg"
   Set-CimInstance -Namespace "root\cimv2\mdm\dmmap" -ClassName "MDM_Policy_Configuration01" -Property @{ParentID="";InstanceID="";OMAURI="./Vendor/MSFT/Policy/Config/Personalization/DesktopImage";Value=$wallpaperPath}

   This command will update the device's configuration and set the specified image as the desktop wallpaper.
