Microsoft has been hard at work to optimize content delivery since the release of Windows 10 and Office 365. While not perfect at the beginning, the offer is now really great and offer many supported methods to ease the huge content that needs to be distributed month after month. Delivery Optimization is a key component included in Windows 10 since the beginning and recently added to Office 365. Combining Delivery Optimization Intune with Windows update for business will greatly help content download from the Internet.

In this post, we will provide details to configure Delivery Optimization for Windows 10 and Office 365, by using Microsoft Intune.

This post is part of a series on Windows Autopilot that will be published in the following weeks. In the next posts, we will cover the following subjects :

What is Delivery Optimization?

Delivery Optimization is a built-in service of Windows 10, and now Office 365, that allows computers under the same network to share downloaded content for monthly updates and bi-yearly upgrades of Windows 10 and Office 365 in a form of peer-to-peer.

The main benefit of Delivery Optimization is to avoid the trouble of managing the downloads of updates to an offline source, like Configuration Manager/WSUS, by allowing Windows 10 clients to download updates directly from Windows Update sources. It then shares it to nearby computers in the desired behavior to prevent overloading the network (LAN and/or WAN).

Whenever Windows Update for Business is used to manage updates, or simply if computers aren’t managed for updates, Delivery Optimization should be put in place to help with bandwidth management.

Delivery Optimization Intune Requirements

For Windows 10

  • All versions of Windows 10 support Delivery Optimization, but 1709 or higher should be used since there were key improvements over the years.

For Office 365

  • Updates must come from Office Content delivery network(CDN)
    • This means not from ConfigMgr or a shared network
  • One of the following must be met:
    • Version 1808 or higher for background updates
    • Version 1908 or higher for installation or user-initiated updates

Configure Delivery Optimization Intune for Windows 10

In the early days of Windows Update for Business, Delivery optimization was configurable within a ring configuration for Windows Update for Business. As seen below, this has been moved to standard device configuration.

To configure delivery optimization for Windows 10, create a new Device Configuration

  • Open the Device Management portal for Intune and click on Devices/Configuration Profiles and select Create Profile
Delivery Optimization Intune
  • Give a name, select platform Windows 10 or later and select profile type Delivery Optimization
Delivery Optimization Intune
  • Next, the detailed configuration can be quite customized for each enterprise.

Download Mode

The most important configuration of Delivery Optimization is Download Mode. This will define how clients will download and share content with others on the network. A bad configuration could kill LAN or WAN connection. There is no definitive answer as to which you should use.

If your enterprise as multiple offices with single NAT per office, then LAN(1) should do the trick. This will allow all computers under that unique NAT to share the content. But on the other hand, if you have a unique NAT for multiple offices, using this option will likely take a lot of bandwidth between your offices when dealing with large updates/upgrades.

The option of Groups(2) should also be considered. This allows some granularity and multiple choices to group computers. This will avoid the limitation of the LAN(1) option.

  • Data Type: string
  • Value: <enabled/>
Delivery Optimization Intune
  • The end result should look like this
Delivery Optimization Intune
  • Assign the configuration profiles to devices and voila

There is another option that is provided from Michael Neihaus blog, to use a custom ADMX to configure this same setting.

Validation of Delivery Optimization usage

Before looking for actual facts that DO is working correctly, a validation of your GPO might be a good idea. Many enterprises did change the behavior of Delivery Optimization because of the early days of the technology. Make sure to remove any GPO that manage Delivery Optimization.

Getting data usage of Delivery optimization takes time. Without monthly updates or major upgrades, not much will happen. But once it gets going, numbers are pretty crazy!

Under Windows Analytics – Update Compliance, there is a dedicated section for Delivery Optimization.
