How to Disable WinHTTP Web Proxy Auto-Discovery

According to Microsoft, the WinHTTP AutoProxy, also known as autoproxy, feature has been available starting with WinHTTP version 5.1 in Windows 2000 Service Pack 3, Windows XP Service Pack 1 and Windows Server 2003. It runs as a service on local computers as well as on network servers. Autoproxy makes it easier for WinHTTP applications to configure necessary proxy settings. This feature takes away the responsibility of knowing proxy settings from the end user.
