How to configure Windows Update to use a proxy server

Synopsis

Windows Update can use an HTTP proxy server. However, configuring Windows Internet Explorer is not sufficient to configure Windows Update because Windows Update uses Windows HTTP Services (WinHTTP) to scan for updates.

You can configure Windows Update to use a proxy server in two ways:

  • Web Proxy Auto Detect (WPAD) settings are configured. The WPAD feature lets services locate an available proxy server by querying a Dynamic Host Configuration Protocol (DHCP) option or by locating a particular Domain Name System (DNS) record. See these articles.
  • Use the Netsh command-line tool (see below)

 

Using the Netsh command

First of all configure Internet Explorer with the correct settings and then open a command prompt (as administrator) and run:

Netsh winhttp import proxy source=ie

This will import the Internet Explorer proxy settings into the WinHTTP service.

To view the WinHTTP proxy settings, use:

Netsh winhttp show proxy

To reset the WinHTTP proxy settings, use:

Netsh winhttp reset proxy
