How to Stop Windows 10/11 from Sharing Updates (Delivery Optimization)

/ 2 min read

Table of Contents

In modern versions of Windows (10 and 11), the Update Center includes a feature called “Delivery Optimization.” Essentially, it is a P2P client that allows your computer not only to download updates from Microsoft servers but also to distribute them to other users on the internet or your local network.

While this helps Microsoft reduce the load on its servers, for the end user, this feature can lead to:

  • Increased internet data usage (critical for USB modems and limited data plans).
  • Higher ping in online games.
  • Reduced overall bandwidth during active distribution.

How to Disable Update Sharing (P2P)

These instructions apply to both Windows 10 and Windows 11.

Steps for Windows 11

  1. Press Win + I to open Settings.
  2. Go to Windows Update -> Advanced options.
  3. Select Delivery Optimization.
  4. Set the Allow downloads from other PCs toggle to Off.

Steps for Windows 10

  1. Open Settings -> Update & Security.
  2. Select Delivery Optimization from the sidebar.
  3. Turn off the Allow downloads from other PCs setting.

Complete Disabling via Registry (Advanced)

If you want to completely stop the “Delivery Optimization” service (DoSvc) so it doesn’t consume resources or start automatically, use the Registry Editor.

  1. Press Win + R, type regedit, and press Enter.
  2. Navigate to the following path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DoSvc
  3. Locate the Start parameter and change its value to 4 (Disabled).
  4. Restart your computer.

Once disabled, the service will be completely inactive. To re-enable it later, change the value back to 2 (Automatic).

Alternative Configuration (Local Network Only)

If you have multiple computers at home, you don’t have to disable the feature entirely. You can allow sharing only within your local network. This will speed up updates for your devices without consuming external traffic for strangers.

To do this, select Devices on my local network instead of “Devices on the Internet and my local network” in the same settings section.

Verifying Status

To see how much data has been saved or consumed by this service, you can click the Activity monitor link on the same settings page. It displays detailed statistics for both incoming and outgoing “Delivery Optimization” traffic.
