    Windows Defender disabled and is unable to start


    Hi guys!

    I finally managed to fix my Windows Defender. I had to restore the service using registry key. And also make changes in the registry using steps mentioned on articles online.

    I restored the WD default registry key through the steps provided here this restored my service of Windows defender.

    Services - Restore Default Services in Windows 8

    It seems that the registry key for WD of Windows 8.1 is same as that of Windows 10.

    I also followed the steps mentioned here:
    [FIX] Windows Could Not Start The Windows Defender Network Inspection Service On Local Computer

    And

    Here:

    Windows Defender Does Not Start in Windows 10 - WindowsInstructed

    So far it's working fine. Will report back if I see anything weird pop up as I did fiddle with the registry keys.

    Thanks for the help davidhk Windows Defender Service Could Not Be Started :)

    windows defender & security center services keep turning off


    Are you running any other AV or did you have one running in the past? If you didn't use an uninstaller for the AV, then the remnants of it could be causing the problem. Normally any time you install an AV it disables Defender by default.

    If you are getting any error codes please list those, that will be helpful in helping you.

    As torre suggested, might be a good idea to do a reset or even a reinstall.

    Windows 10 - Clean Install - Windows 10 Forums

    There are also some suggestions listed here:

    Windows Defender Service Could Not Be Started

    Windows Defender disabled and is unable to start


    OK. I am not sure if you can complete the steps below.......................
    In the search box, type services.msc > Enter
    Items in the Services box are listed alphabetically.
    Scroll down to Windows Defender Service...........................
    at Status heading, it should be.................................... Running
    at Startup type, it should be......................................... Automatic

    If that is not what yours said, right click at Windows Defender Service > click Properties >
    can you change the Startup type to Automatic and Service status to Start ?
    If yes, do so and click OK when done.
