    How to Turn On or Off Windows Defender in Windows 8 and 8.1


    information   Information
    Windows 8 comes with a new version of Windows Defender which is the re-branded "Microsoft Security Essentials" (MSE). When Windows Defender is on, you're notified when viruses, spyware, malware (malicious software), or potentially unwanted software try to install or run on your PC.

    This tutorial will show you how to turn on or off Windows Defender in Windows 8, Windows RT, Windows 8.1, and Windows RT 8.1.

    You must be signed in as an administrator to be able to do the steps in this tutorial.

    Note   Note
    In order for Windows Defender to run, it will require that the Windows Defender Service remain "Started" (running) and set to "Automatic".

    How to Start, Stop, and Disable Services in Windows 8

    warning   Warning
    Some 3rd party antivirus (AV) programs may turn off Windows Defender when they are installed to be used instead, and will not allow Windows Defender to be turned back on until the 3rd party AV has been completely uninstalled.







    OPTION ONE
    To Turn Off Windows Defender in Windows 8

    1. Open the Control Panel (icons view), and click/tap on the Windows Defender icon.

    2. In Windows Defender, click/tap on the Settings tab, Administrators in left pane, uncheck the Turn on Windows Defender box, and on Save Changes. (see screenshot below)

    NOTE: If you click on this message balloon while open, it will turn on Windows Defender again.

    Hello Bailey, and welcome to Eight Forums.

    When Norton is installed it will turn off Windows Defender by default. You would need to uninstall Norton to be able to turn on Windows Defender. If Norton doesn't uninstall normally for some reason, then you could use the Norton Removal Tool to do so.

    Hope this helps,
    Shawn

    Dear Admin,
    Kindly assist me. Bought my PC with windows 8, uninstalled norton, but each time I try to Turn on windows defender the computer opens the system files and I do not have any idea of what to do with these system files as nothing seems clear and relevant as to indicate which one to open for the defender to be active. Please help.

    Dr. Josh,

    It sounds like your system may be infected. Either way, I would recommend to reset Windows 8 to start fresh to be safe. Be sure to back up anything that you do not want to lose first to another location.
