If you are a Windows Systems Engineer looking to manage and optimize network bandwidth for Delivery Optimization (DO), you might come across the Set-DOPercentageMaxForegroundBandwidth cmdlet in PowerShell. This cmdlet is used to configure the maximum percentage of network bandwidth that Delivery Optimization can use for foreground downloads. This article will guide you through the practical steps of using this cmdlet in a Windows environment.

Understanding Delivery Optimization

Delivery Optimization is a peer-to-peer client update service that uses PCs, both local and non-local devices, to deliver updates to Windows 10 and Windows 11 devices. It helps in reducing the bandwidth consumption by sharing the update files across multiple devices.

Prerequisites

• Windows 10, Windows 11, or Windows Server 2016 and later.
• PowerShell 5.1 or later.

Example 1: Setting the Maximum Foreground Bandwidth to 50%

To set the maximum percentage of network bandwidth that Delivery Optimization can use for foreground downloads to 50%, you can use the following PowerShell command:

Set-DOPercentageMaxForegroundBandwidth -Percentage 50

Example 2: Setting the Maximum Foreground Bandwidth to 75%

If you want to allow Delivery Optimization to use up to 75% of the network bandwidth for foreground downloads, you can use:

Set-DOPercentageMaxForegroundBandwidth -Percentage 75

Example 3: Viewing Current Configuration

To view the current configuration of Delivery Optimization, you can use the Get-DOConfig cmdlet:

Get-DOConfig

This will display the current settings, including the maximum foreground bandwidth percentage.

Example 4: Resetting to Default Settings

If you need to reset the Delivery Optimization settings to their default values, you can use the following command:

Reset-DOConfig

Troubleshooting

1. Permission Issues: Ensure you are running PowerShell as an administrator.
2. Cmdlet Not Found: Make sure you are using a supported version of Windows and PowerShell.

Conclusion

Using the Set-DOPercentageMaxForegroundBandwidth cmdlet in PowerShell allows you to control the network bandwidth used by Delivery Optimization for foreground downloads, helping you manage network resources more efficiently. By following the examples provided, you can easily configure and optimize your network settings to suit your needs.
