    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.

    Windows Defender'This Service Couldn't 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.

    Reset Windows 10 - Windows 10 Forums

    Windows 10 - Clean Install - Windows 10 Forums

    There are also some suggestions listed here:
