    Windows 10 sign in error 0x80070426


    Having trouble singing in to the Microsoft store and mail apps I have tried searching these forums and tried several things , none seem to work , I can access my mail account via the internet and I can find apps without using the store app. What I need to know is WHY IS THE HELP SYSTEM NON EXCISTANT IN WINDOWS just have a website , What this error code is ((activation error?) start>settings>update&security>Activation shows activation is via ms account . ) Why just a number and no description of error ? is there a list of errors, I have submitted via the feed back hub but as I cant sign in don't know if it is sending.

    :)

    Software Protection is set to Automatic Delayed. The status on the list of services does not show it running. The status on the properties showed it running, then not running. If that sounds strange, look at the status of the Security Center on both windows, it's showing both:

    Error code: 0x80070426 when opening Windows Defender

    Hi,

    The error code 0x80070426 can be caused by corrupted system files when an update was performed on your device or Windows Defender detects a third-party antivirus software is also installed. We suggest that you check your PC if a security is installed or
    not. Once third-party antivirus has been removed, you may need to turn it manually back on. To do this, follow the steps below:

    • Press the Windows + Q key from the keyboard to bring up the charms search.
    • In the Search box, type Windows Defender, then press
      Enter.
    • Click Settings and make sure that there's a check mark on
      Turn on real-time protection recommend
      .

    Feel free to respond if you need additional assistance.
