How to Enable Multipath RDP On Windows 365 Cloud PC Using Intune PowerShell Script HTMD Blog

In this article let’s quickly examine how enable RDP Multipath on Windows 365 Cloud PC use Microsoft Intune. Enable Multipath RDP on Windows 365 Cloud PCs ensuring that remote sessions can use both TCP And UDP transport channels, improving the robustness and performance of the connection. This is especially important for users accessing their Cloud PC over a variable network, as Multipath allows Remote Desktop Protocol (RDP) to dynamically switch and balance between transports for a smoother experience. Rather than relying solely on manual configuration, administrators can automate these settings through Intune with PowerShell scripts.

By making use of PowerShell Intune scripting capabilities, IT admins can remotely push registry changes to all targeted Cloud PCs. Specifically, enabling Multipath RDP requires setting the registry key below HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\RdpCloudStackSettings with the values ​​that define transport behavior.

Deploying this as a PowerShell script via Intune ensures configuration implemented consistentlywithout requiring user intervention, while enabling version control and updates. After updating a registry key, users must disconnect and reconnect to their registry key Windows 365 Cloud PC host the session for the changes to take effect.

To implement this, an administrator simply needs to create and upload a script in Intune that creates or changes the necessary registry values, such as settings SmilesV3 Activation Threshold to optimize Multipath activation. Once the script is assigned to the appropriate Cloud PC group, Intune will handle execution and reporting. This approach not only simplifies implementation but also provides visibility into compliance, helping organizations deliver more value reliable and an optimized RDP experience across their Windows 365 environment.

Why Enable Multipath RDP on Windows 365 Cloud PCs

Here is a very simple table that explains this benefit than possible Multipath Remote Desktop Protocol (RDP). on Windows 365 Cloud PCs.

How Does Multipath RDP Work?

Multipath RDP uses multiple network routes, which are identified via Establishment of Interactive Connectivity (ICE)to make the connection more reliable. This route may involve options such as UDP with stun or UDP with Relays. If the primary connection is lost, it will automatically switch to the backup route.

• And if any routes are disconnected such as when the network goes down completely, the system will continue to try to reconnect as soon as the network returns.

Create a Platform Script in Intune to Enable Multipath RDP

To activate Multipath RDP on Windows 365 Cloud PC use Aligned PowerShell scriptfollow these steps. I will configure it using Platform script. Entered into Microsoft Intune Admin Center with your admin credentials.

• Navigate to Device > window > Scripts and remediation
• Click Platform script > +Add

In Basics details panel, we can name the PowerShell Script “Enable RDP Multipath on Windows 365 Cloud PC.“Providing a brief description of the script would be helpful. I recommend using the following:”RDP Multipath improves the reliability and performance of Windows 365 Cloud PC connections by intelligently utilizing multiple network paths.” and click Next.

Write a PowerShell Script to Enable Multipath RDP on Windows 365 Cloud PC

Let’s keep it short PowerShell script from scratch to enable multipath RDP on a Windows 365 Cloud PC. This script will add the necessary registry keys HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server. Save the script with a .ps1 file extension.

<#
.SYNOPSIS
  Configure RDP Multipath setting for Windows 365 Cloud PCs

.DESCRIPTION
  This script creates/updates the registry key:
  HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\RdpCloudStackSettings
  with the value:
  SmilesV3ActivationThreshold (DWORD) = 100

# Define registry path and values
$RegPath = "HKLM:\SYSTEM\CurrentControlSet\Control\Terminal Server\RdpCloudStackSettings"
$Name = "SmilesV3ActivationThreshold"
$Value = 100

# Ensure registry path exists
if (-not (Test-Path $RegPath)) {
    New-Item -Path $RegPath -Force | Out-Null
}

# Create/Update the registry value
try {
    New-ItemProperty -Path $RegPath -Name $Name -Value $Value -PropertyType DWord -Force | Out-Null
    Write-Output "Registry value $Name set to $Value successfully."
}
catch {
    Write-Error "Failed to set registry value: $_"
}

Notes! I’ve uploaded it PowerShell script for me GitHub Reposso please check it out for your needs. Download from here : EnableRDPMultipathSettings_Windows365CloudPCs.ps1. To disable RDP Multipath early (opt out) use this script DisableRDPMultipathSettings_Windows365CloudPCs.ps1

In Script settings panel, we can set the configuration according to our needs. The first option is mandatory, we have to browse and select our savings PS Script Here.

• Script location – Browse and select a saved script EnableRDPMultipathSettings_Windows365CloudPCs.ps1
• Run this script using login credentials – NO
• Implement script signature checking – NO
• Run the script on PowerShell Host 64 bit – Yes

On the next page, save default scope tag. If there are custom coverage tag available based on your requirements, you can select it for implementation of this script.

Click Next and assign the script to HTMD CPC – Test. You can click Add group and select the desired Cloud PC device group in Included groups part.

In Review + create panel, carefully check all settings for Enable RDP Multipath on Windows 365 Cloud PC Scripts and remediation. Once you confirm everything is correct, select it Make to implement changes.

Monitor Deployment of Enable Multipath RDP on Windows 365 Cloud PCs

This Intune PowerShell script has been deployed to a Windows 365 Cloud PC group (HTMD CPC – Test). The policy will come into effect as soon as possible after the device is synced. To monitor policy implementation status of Intun Portalfollow the steps below.

• Navigate to Device > window > Scripts and remediation > Platform script

Search “Enable RDP Multipath on Windows 365 Cloud PC” Script The implementation status of this script can be seen below Summary status. We can see that both Devices and Users status have Succeed.

End User Experience

We need to do it inspect whether the Intune PowerShell script has enabled RDP Multipath on the Windows 365 Cloud PC. To do this, log in to the targeted Cloud PC and open Registry to check whether the required entries have been made. Follow the path below: SmilesV3 Activation Threshold DWORD value should be set to 100.

• Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\RdpCloudStackSettings

Now, open it Windows Application and connect to your Windows 365 Cloud PC. Once connected, click the Windows 365 icon in the top left corner and select Connection Information. This will open the Remote Desktop pop-up; click View Details. Here, you will see that Transport protocol displayed as UDP – Multipath. This confirms that the PowerShell script deployment works as expected!
