    Windows Defender stopped working after Windows 10 upgrade

    I installed Windows 10 Technical Preview over Windows 8.1. I just want to upgrade and test how this new OS is and now there is some issue with Windows Defender. It is not working.

    I tried to turn that thing on but most of its options are great out. And sometime I am also getting an error on the screen. This says that Windows Defender is turned off. And when I try to turn it on it fails to work.

    I want some help here to make this thing work. I tried a lot but it is not working.

    If Windows Defender is giving you an error here then it is good to stick with some third party security software. There are ample of them which you can use and also they give you lot of features. Like you can use a free edition of AVG antivirus. Windows Defender is very basic in usage.

    It is not offering you any high end security solution. Compare to that using a third party free antivirus will be lot more easily to use. Just go for AVG it is free.

    I also think you must go with third party security software which will surely help you a lot in fixing the problem.

    There are some basic steps you can try out to resolve the issue if you are really willing to use Windows Defender. For the first go in Services which you can find in Administrative Tools inside control panel and check that the Windows Defender Service is turned or not. You can do that by right clicking in the same.

    Then you can go in Action Centre and in that go in Security. And see that WD is active there or not.
