Windows 10 Windows Update Delivery Optimization

Category: Administration

Prior to Windows 10, updates to Windows and other Microsoft products were downloaded only from Microsoft servers. Windows Update connected to Microsoft servers, checked if any updates were available, and if available, downloaded them to your computer.

This has changed in Windows 10, which introduces the Windows Update Delivery Optimization feature, wherein your computer may get updates from or send updates to neighboring computers or computers on your network. Although this would mean that you get updates much faster, it would also possibly increase your proxy/bandwidth utilization causing degradation in your proxy performance.

You can disable and turn off the Windows Update Delivery Optimization (WUDO) feature in Windows 10.

To turn off the feature, follow these steps:

  1. Open Settings.
  2. Click Update and Security.
  3. Under Windows Update, click Advanced Options on the right side of the window.
  4. Under Updates from more than one place, click Choose how updates are delivered and then move the slider to OFF to disable WUDO. In moving the slider to OFF, your PC cannot download updates from anywhere other than Microsoft servers.
  5. If you would like to download updates from PCs to your network, keep the slider in the ON position, and select PCs On My Local Network. The other option is PCs on My Network and PCs on the Internet. This is the option that is possibly causing extra utilization of your bandwidth through your proxy.

 

Windows Update through the proxy

Category: Administration

If updates fail to run through the proxy, you will need to manually set proxy settings for Windows Update. Additionally, it may be necessary to bypass authentication for certain URLs in order for the updates to pass.

Setting Proxy Configuration for Windows Updates

  1. You can import proxy settings from Internet Explorer by opening a command prompt and entering the following:
    • netsh winhttp import proxy
  2. Additionally, you can manually set the proxy by opening a command prompt and entering the following:
    • netsh winhttp set proxy <Proxy Server>:<Port> “<Exclusion List>”

Bypassing Authentication for Windows Updates

  1. In the CyBlock interface, go to User Management – Authentication and click the Bypass tab.
  2. Add new bypass entries by clicking the green green button button.
  3. Create two separate entries using the following configurations (with asterisks as wildcards).
    • URL or Domain: *.microsoft.com             |  User-Agent: *
    • URL or Domain: *.windowsupdate.com   |  User-Agent: *
