  2. WINDOWS DEFENDER is turned off

    Hi Ahmed,

    Since you're not able to turn on Windows Defender as well, we'd like to know if you have made any changes recently prior to this issue. In the meantime, you may follow the steps below on how to turn on Windows Defender manually:

    • Type Windows Defender in the Search bar and press
      Enter.
    • Go to Settings and make sure that the Turn on real-time protection recommended option is turned on.
    Same thing with the other members who are having the same issue, we suggest that you check if the service was setup to
    Automatic in the Services option. Please follow the steps that we've provided last
    September 3, 2017.

    Let us know how if you were able to turn it on properly by changing the Startup type to Automatic.

  3. How to turn on Windows defender in Windows 10

    Hello,

    I realize the inconvenience you are experiencing with Windows 10. I will certainly help you.


    Windows Defender is the default real-time (always on) protection program in Windows 8, 8.1 and 10.

    If there are any third party security software installed, then Windows Defender will get disabled automatically.

    I suggest you to follow the steps below and check if it help:


    • Open Settings by either clicking on the Settings icon on the Start menu or simultaneously pressing Windows and I keys.

    • Click on Update & Security.

    • Click on Windows Defender, and on the left right side, turn on.
    Hope this helps in resolving the issue. If the issue persists, do get back to us. We will be happy to assist you.

    Thank you.

    Turn On Windows Defender Block Suspicious Behaviors in Windows 10


    The DWORD is set to 0 and I cannot get the process you suggested in the "NOTE" portion of the tutorial to work. Two attached screen shoots will show the before and after attempts to change the Permissions necessary for access to the DWORD change.
