Windows Update Optimization

Recently I discussed the Windows Update Peer to Peer functionality with one of my customers. And MS also added some GPOs to control this better.


In Windows Update -> Advanced Options -> Choose how updates are delivered
You will find the plain simple setting for this. But you can do much more.

 

 

What it is for:

Windows Update Delivery Optimization enables you to download Windows updates and Windows Store apps from sources other than Microsoft. This can help you get updates and apps more quickly if you have a limited or unreliable Internet connection. If you own more than one PC, Delivery Optimization can reduce the amount of Internet bandwidth that is required to keep all your PCs up-to-date. Delivery Optimization also sends updates and apps from your PC to other PCs on your local network or on the Internet.

You can use Group Policy to configure Windows Update Delivery Optimization. To do this, follow these steps:

1. Download the Administrative Templates (.admx) file for Windows 10 from the following Microsoft Download Center website:
   
   Administrative Templates (.admx) for Windows 10 Version 1607 and Windows Server 2016
   
   Administrative Templates (.admx) for Windows 10 and Windows 10 Version 1511
2. Copy the following files to the SYSVOL central store:
   • DeliveryOptimization.admx from C:\Program Files (x86)\Microsoft Group Policy\Windows 10\PolicyDefinitions
   • DeliveryOptimization.adml from C:\Program Files (x86)\Microsoft Group Policy\Windows 10\PolicyDefinitions\en-US
3. Start the Gpeditor tool.
4. Browse to the following location:
   Computer Configuration\Administrative Templates\Windows Components\Delivery Optimization
5. Make the following Windows Update Delivery Optimization settings, as appropriate.

Whats new in 1607:

There are also additional GPO settings available in 1607 which added more control on this (The support article refer to an obsolete article at the end!) This is the new replaced blog entry from Michael Niehaus.
