    Defender is not responding: Connectivity problem


    According to the Insiders thread 15063.11, this bug is also affecting 14393.970 and the given solution works OK. I was not able to reach version .603 because a message was saying Internet connectivity problem. Thanks!

    I have many problems with Defender since about 4-5 weeks and all reported bugs by Insidres are also affecting RS-1.
    Insiders solution given by Vincentwindows:
    Temp fix:
    Delete following registry key:
    Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MpSigStub
    Cumulative Update KB4016250 for Windows 10 v1703 Build 15063.11 - Page 8 - Insider - Windows 10 Forums

    WINDOWS DEFENDER

    THE PC TELLS ME THAT my Windows Defender (W10) is out of date. When I try yo update it, after a long time I get the message that the app took to long to respond. Otherwise the Internet connection works fine. Can I reinstall the Defender and how to do it?

    3rd Party Apps (like Google Chrome, Steam, torrent clients,etc) not able to connect to Internet on Windows 10

    Hello,

    I just upgraded my OS from Windows 8.1 to Windows 10. But I have a major problem: 3rd party are not able to connect to the Internet, even though I have allowed them through the Firewall and Windows Defender.

    I have also re-installed those apps, but have been unable to solve the issue.

    Please respond at the latest as to how to solve the problem.

    Thanks.

    P.S.

    My Internet is working well on Microsoft Edge. No problem with the network connection.
