Get an app to open this 'windowsdefender' link

[Lasse_Hvilsted]

So i have just updated my pc from windows 10 to 11 and saw that the little windows security icon in the bottom right corner showed some recommendations. I tried opening up windows security but it wouldnt. So i navigated to it through the settings menu and then it told me this "Get an app to open this 'windowsdefender' link". I have tried nearly every guide on youtube but nothing has worked as of yet.
i should also mention that i cant find the windows security app under the apps section in settings

Hi @Lasse_Hvilsted 

Automatically diagnose and fix problems with Windows Firewall - Microsoft Support

That should help, we'll see?

[#3]

ty so much. It seems to be the problem as it wont allow me to enable windows firewall. But the fact is i have just reset my pc (erased everything) and upgraded to windows 11 and i havent enabled any other firewall, that i am aware of.
It tells me that it cannot be enabled because of an existing group policy or because i am using another firewall program.

@Lasse_Hvilsted 

But you downloaded the tool I shared?

[#5]

Here is the whole story. I got scammed via discord because of social engineering. Which lead me to run a .exe file (i know, extremely stupid). The .exe file somehow took my discord credentials and google acount info. Thats the reason that i erased everything from my drives and reinstalled windows.
But i did indeed download the tool. It said it could not enable the windows firewall "because of an existing group policy or because another firewall is running". But i havent enabled any other firewall.

First, check Windows activation - connect to your Microsoft account.

Already have tried that. Didnt work

Fix: Windows Defender blocked by Group Policy - Unblock in 4 Steps (malwarefox.com)

It is still worth analyzing it 🙂

[#14]

Didnt help either... Still same message when i try to open it up

[#15]

I first tried the Group Policy Editor, it didnt work. I searched for it and ran the editor. But then i gave me an error message and now i cant find it again.
Then i tried the Regestry Editor but there were no key in the path called "DisableRealTimeMonitoring"
Then i tried the powershell command but that didnt work either.
And i cant do the last one cause i cant open the security

[#16]

I got the group policy editor to work and changed the property of the "Turn off Microsoft Defender Antivirus" as the guide showed. Then i ran the firewall tool but the same message came up. So apparently my computer is running an firewall that i dont know of

[#17]

@Lasse_Hvilsted 

Check the task scheduler - there you should see the running tasks by another antivirus.

[#18]

Cant really find anything but then again i am not really familiar with the tool and i dont know what exactly i am looking for

[#19]

@Lasse_Hvilsted 

Preferably - go to your computer manufacturer's technical support - they are the most appropriate to fix this problem.

Because you've taken a lot of steps – no solution.

I dont know why it is acting up. I just went to Control Panel -> System and Security -> Windows Defender Firewall -> Customize Settings. And there i can see that Windows Defender Firewall is enabled on both private- and public network setting
