Overview​

This script disables Windows' peer-to-peer update sharing service.

Delivery Optimization 1 2 3 4 5 6 7 or Windows Update Delivery Optimization 6 7 is a Windows feature that distributes Windows and Microsoft Store app updates through peer-to-peer sharing 1 3. This feature enables Windows to download updates not just from Microsoft's servers but also from other computers 1 7. Microsoft states that its goal is to serve Windows and Store apps faster 7

By default 2, Windows downloads updates from and shares them with:

  • Computers on your local network 3 7
  • Unknown computers across the internet 7

The feature affects updating system components including:

  • Windows system updates 1 7
  • Microsoft Store apps 1 7
  • Microsoft Defender updates 1 7
  • Microsoft Edge updates 1
  • Xbox Game Pass (PC) 1
  • Win32, Microsoft 365 apps 1
  • Configuration Manager Express updates 1
  • Dynamic updates 1
  • MDM Agent 1
  • Windows Package Manager 1
  • MSIX Installer 1

This script disables the service that manages this functionality 2 3 4 5. By default, this service is set to start automatically when Windows boots up 2. This script alters that behavior, ensuring it doesn't run unless explicitly started by the user.

When active, this service manages update downloads and sharing by connecting to various Microsoft endpoints 3.

It collects sensitive data including:

  • Policies 3
  • Content details 3
  • Device specifications 3
  • Information about other Windows devices 3
  • IP addresses 4

It shares your data by continuously communicating with Microsoft servers 3 8.

This script enhances privacy by:

  • Preventing your computer from uploading updates to other computers
  • Blocking downloads from untrusted sources
  • Stopping the service from collecting data about your device and network 3 4

This script also increases your security by reducing exposure to inbound connections 6.

It improves system performance by reducing bandwidth usage and stopping continuous background upload and download tasks.

However, this is a core Windows service that manages essential system functions. Disabling it may break Windows features and programs. This service is known to cause issues with Windows Updates and Microsoft Store downloads when disabled. You should use this script together with other scripts that disable Delivery Optimization (search for "Delivery Optimization") to avoid these side-effects.

The known side-effects include:

  • Windows Update failures 8 9, causing errors with codes 0x80004002 8 10 and 0x800f0988 10
  • Microsoft Store app update and downloads failures 8 9 11, causing errors with code 0x800704C6 8
  • Third-party update software, such as Windows Update MiniTool (WUMT) 12 13, may fail to function properly.
Caution

Disabling this service may cause issues with Windows Updates and automatic app updates if other Delivery Optimization settings are not correctly configured.
