Can't update Windows 7 - Windows Update Client failed to detect with error 0x80072efd

    Question

  • Tried the following:
    1. Update works if I bypass the router, ie. connect the PC directly to modem.
    2. It also works from different ISP, through router (at work).
    3. Format disk & Reinstall windows 7
    From windowsupdate.log:

  • Hi,

     

    Try to remove the proxy server entry from the WinHTTP proxy configuration for Windows 7:

     

    1.    Click Start, and then type cmd in the Start programs and files box.

    2.    Right-click cmd.exe in the Programs list, and then click Run as administrator.

    Note If you are prompted for an administrator password or confirmation, type the password or click Continue.

    3.    Type the following command and then press Enter:

    netsh winhttp show proxy

    Note The proxy setting is listed next to Proxy Server. If there is no proxy server, Direct Access <no proxy server> is shown in the Command Prompt window.

    4.    To remove the listed proxy setting, type the following command and then press Enter:

    netsh winhttp reset proxy

    5.    Click Start, click All Programs, click Windows Update, and then try to download and install updates again.
