## Overview
Delivery Optimization is a powerful and useful tool to help enterprises manage bandwidth usage for downloading Microsoft content. It's a solution designed to be used in large-scale environments with large numbers of devices, various content sizes, etc. Delivery Optimization is native to currently supported versions of Windows and provides default configuration to get the most out of the typical customer environment. Delivery Optimization is used to deliver many different types of content, so Microsoft customers enjoy the best possible download experience for their environment. There are three components to Delivery Optimization:

One of the most powerful advantages of using Delivery Optimization is the ability to fine-tune settings that empower users to dial in Microsoft content delivery to meet the needs of specific environments.
## Monitoring The Results
## Monitoring the Results
Since Delivery Optimization is on by default, you're able to monitor the value either through the Windows Settings for 'Delivery Optimization' using Delivery Optimization PowerShell [cmdlets.](waas-delivery-optimization-setup.md), and/or via the [Windows Update for Business Report](../update/wufb-reports-workbook.md) experience in Azure.

|Virtual Machines/physical devices| 2 |
|Windows OS version | Windows 10 (21H2) and Windows 11 (21H2) |
|RAM | 8 GB |
|Disk size | 127 GB |
|Network | Connected to same network, one that is representative of the corporate network. |
|Pause Windows Updates | This controls the test environment so no other content is made available during the test, and potentially altering the outcome of the test. If there are problems and no peering happens, use 'Get-DeliveryOptimizationStatus' on the first machine to return a real-time list of the connected peers. |
|Ensure all Store apps are up to date | This helps prevent any new, unexpected updates to download during testing. |
|Delivery Optimization 'Download Mode' Policy | 2 (Group)(set on each machine) |
|Delivery Optimization 'GroupID' Policy | Set the *same* 'GUID' on each test machine. A GUID is a required value, which can be generated using PowerShell, '[[guid]::NewGuid().](https://devblogs.microsoft.com/scripting/powertip-create-a-new-guid-by-using-powershell/)'. |
|**Required on Windows 11 devices only** set Delivery Optimization 'Restrict Peer Selection' policy | 0-NAT (set on each machine). The default behavior in Windows 11 is set to '2-Local Peer Discovery'. For testing purposes, this needs to be scoped to the NAT. |
