  1. Defender update download errors on both antivirus and antimalware


    Ever since the latest update I got for my windows home version about a week ago I have been getting an error message 0x80070643. It first started on an update for the antimalware and now I am also getting the same message for the virus updates.

    What good is using windows defender to protect my computer if when you make updates to the windows home version it screws up the virus protection.

    Please let me know when you are going to fix this problem as soon as possible. I really don't want to have to restore my computer again to fix this problem. I lost all my information the last time one of your updates trashed my computer.

    :)

    As with previous antimalware client updates, the update doesn't show in Update History. It can be seen in Reliability History.
