    In that case, you may need to refresh or reset Windows 8.1 to fix it. It sounds like Kaspersky may have hosed it.

    Thank you!
    I found an uninstall program to remove the remnants of McAfee that was uninstalled on another forum, and your steps here helped me get Windows Defender turned on again!

    Hello Jan, and welcome to Eight Forums.

    I'm glad it was able to help.

    Was it the same tool in the second link in the red warning box at the top of the tutorial? This way I can add it if not to help others.

    Hey I can not turn on my windows defender. I have followed the instructions. I had Mcafee on my computer and I took it off because I think it's cause a lot of problems for my computer, but now it will not let me turn on my windows defense. What should I do now? Thanks in advance.

    Hello Cora, and welcome to Eight Forums.

    If you have not already, see if using the McAfee Consumer Product Removal tool may be able to help let you afterwards.

    I have done this already...When I go to my control panel there is a window defender folder but when I click on it. It said nothing there.

    In that case, you may need to refresh Windows.

    I just re-installed windows 8.1 after a terrible experience with 10.
    Disabled defender (by disabling it's service), action center and such annoying things.

    But after restarting because of windows updates the defender service is set to autostart and running again. And I can't disable it anymore, because the options are dimmed. That's really weird/troubling.

    I disabled real-time protection as showed in this guide, but I want it totally disabled to don't waste any resources (also who knows when it enables itself). The warning icon also annoys me...

    What do I need to do?

    I tried it from command line to (sc config WinDefend start=disabled)
    But I got access denied.

    Hello Avada,

    Did you run the command in an "elevated" command prompt?
