How To Fix Windows Update Error 80072EFD

The answer is to disable proxy server of Windows Update:

1) Open an elevated Command Prompt window – click the Vista Orb (Start button), type command prompt, right click the Command Prompt shortcut in the Program list and select Run As Administrator.

2) To display the current proxy setting of Windows Update, execute this command:
netsh winhttp show proxy

3) If the proxy server is shown in the “show proxy” result, then execute this command to disable the Windows Update proxy setting:
netsh winhttp reset proxy

The “reset proxy” will effectively configure WinHTTP proxy server setting to DIRECT (meaning to direct access Internet and no relying on a proxy server).
