    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

    Hotkey comes back


    This is a temporary solution because hotkey is back next morning. Stuck at .603 and not able to reach .701 or higher. Same message: Screenshot.
