    SearchApp.exe is always connected via TCP. I can see it on netstat and performance manager under network. If I reboot, it pops backup. I cannot disable or kill the service. Very bizarre. I would post a screenshot but this site will not allow me to upload images for some reason.I hate Microsoft.

    Cortana Won't Connect

    Hi,

    To better assist you, what are the troubleshooting steps have you done so far? Have you tried
    resetting and re-configuring
    your
    TCP/IP Settings? If not, we suggest that you do so. Kindly perform these
    methods of troubleshooting and check if Cortana can connect to the internet after performing these methods:

    Method 1: Reset TCP/IP

    To do this, follow these steps:


    • Run
      Command Prompt
      as
      Administrator.

    • Run
      this command:

      • netsh int ip reset
        and hit
        Enter.

    Exit
    Command Prompt
    and
    monitor your Network Connection.

    Method 2:
    Reconfigure TCP/IP

    To do this, follow these steps:


    • Run
      Command Prompt
      as
      Administrator.

    • Run
      these following commands:

      • netsh int tcp set heuristics
        disabled

      • netsh int tcp
        set global autotuninglevel=disabled

      • netsh int tcp set global
        rss=enabled

    Update us on how it goes.

    Regards.

    Windows 10 silently establishing connections to host at hk2-dspcdn to download random data

    Hi,

    Last night I just noticed my Internet connection was slow while trying to play a game and watching some youtube videos. At first I thought it was my ISP, but then I closed all the open applications and while
    monitoring my network using (resmon), the PC was still downloading data while everything was turned off!

    A quick netstat with:

    netstat -a | find "EST"

    Shows about 10 connections being made to these host:

    hk2-dspcdn

    hk2sch13002183

    Here's the current output:

    This is with me just booting up the PC, haven't even turned on the browser yet.

    A quick google shows this is owned by Microsoft.

    Has anyone else experience this?

    Does anyone know why Windows 10 is retrieving data silently from this host, it's not a trivial amount either, I logged about 2GB of downloads?

    And yes I've got all automatic updates turned off, as well as allow update p2p sharing turned off.

    I'm running Windows 10 Pro. Version 1607, OS Build 14393.351

    Thanks.
