Windows Defender

    Question

  • Hello,

    My windows defender in Win 10 has stopped working and the headline message I get in the pop-up is...

    "this app is turned off by group policy"

    How do I edit group policy to get defender working again?

    Or is their a program that could do it for me?

    I can usually get over most problems that arise but I am stumped with this one.

    Can anyone help please.

  • Hello my friend !

    The message you have received indicates that the Windows Defender is being disabled by a Group Policy Object!

    To fix this problem up :

    -If your computer has not been joined to an Active Directory Domain : (Means it is a WorkGroup)

          1- Open Run via holding Windows Key + R

          2- Type Gpedit.msc

          3- Go to the following directory :

               Computer Configuration/Administrative Templates/Windows Component/Windows Defender

          4-As seen in this picture you would see a setting entitled Turn of Windows Defender.

          5-Double click on the setting you will see a dialogue box as the following:

          6-Ensure it is being configured as Not Configured or Disabled.

          7-Click OK and close Local Group Policy Editor.

          8-Open a Command Prompt.

          9-Type 

    :-> Gpupdate /Force

  • Hello again mate please answer my questions:

    Is your computer a member of an Active Directory Domain ? (It is not if its a Home PC you have bought form Best Buy - Asus and etc or if you have installed the OS yourself)

    Do you have any other Anti-Malware software like Nod32 or Kasper-Sky ?

  • Ben,

    I have followed your instructions to the letter several times but with no success.

    When I have opened a command prompt and entered Gpupdate /Force the computer works and I get the reply on the screen of -----

    Computer policy update has completed successfully

    User policy update has completed successfully

    -----

    I have tried re-booting after this but I still cannot get Windows Defender to run.

    I am getting the same message as before----"this app is turned off by group policy"

    What else do you suggest??

    Regards

    G

  • Simon,

    Many thanks for your info but I am sorry I am just a layman and can fix most problems but this is beyond me. Your info must be good but I am unable to understand it. What I need, f it means changing the registry, a step by step instruction on how to get my Windows Defender to run. As I said your info is good but my understanding of the registry is very limited. I can go through the registry deleting any mention of a program that I have deleted and can find things to be altered if I am told where to look and what to do when I find it. I should have replied to Ben loghmanian some time ago but I had to go away over the holiday period and have only just returned.

    So if you are reading this Ben I apologise.

    Regards

    G
