Some Windows users reported that their Windows Defender Firewall is using settings that make the device unsafe. They noticed this in their computer’s Windows Security > Firewall & network protection page. This raises many questions, and users want to know how they can resolve this issue. In this post, we are going to talk about ways you can remedy this issue.
Following are the error messages users see.
Windows Defender Firewall is using settings that may make the device unsafe.
Microsoft Defender Firewall is using settings that may make the device unsafe
Let us talk about them in detail.
The first thing you should do is click on the Restore Settings placed right below the error message and see if the issue is resolved. Sometimes, Windows revert back the misconfigured setting to what it should have been in the first place just by clicking on that very button. You should do the same. In case the issue persists, move to the next solution.
Hopefully, this will do the job for you.
Next up, we need to configure some registries to change the permission to everyone. Registry Editor is a built-in app that allows you to configure your Windows Operating System. To change the permission, open Registry Editor and navigate to the following location.
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BFE
Right-click on BFE and select Permission. Click on Add, type “Everyone” and click on Check Names. Select Everyone from the Groups or user name, click on Full Control, and click Apply > Ok. Close Registry Editor and open Windows Security. Hopefully, this will do the trick for you.
Since we don’t know what is causing this issue or which settings are misconfigured, one of the things you can do is reset Windows Firewall. There are various ways to do the same, we see two different methods, so, you can pick the one you like.
Alternatively, you can use a command to have the same effect. To do the same, open Command Prompt as an administrator and then run the following command.
netsh firewall set opmode mode=ENABLE exceptions=enable
Hopefully, this will do the trick for you.
Control Panel\All Control Panel Items\Programs and Features
Hopefully, this will do the job for you.
A virus or malware can stop Windows Defender from performing its tasks. If you have a third-party antivirus, go ahead and run it, but even if you don’t have an external tool, the built-in Windows Antivirus is capable enough to scan and delete malicious files.
Note: Microsoft Defender Antivirus (offline scan) was called Microsoft Defender Offline Scan.
Wait for the antivirus to identify and remove malware – if found.
Yes, you should allow Windows Defender Firewall to run on your computer all the time. You should not disable the Windows Firewall. Windows Defender Firewall is a great way to keep your device secure and if you are afraid of viruses, malware, or any security threat (which you should be), then you must keep the feature on. However, if you have some other security app or third-party antivirus, then you can disable the feature. But if you don’t have any security program or the one you have doesn’t have a built-in Firewall, disabling the Windows Defender Firewall will make your device vulnerable to threats. Long story short, you need a firewall to safeguard your computer, but it doesn’t have to be Windows Defender.
If you can’t turn on Windows Defender Firewall, then maybe there is some kind of security program on your computer that stops you from taking the action. If that’s not the case, then maybe some of your computer’s files got corrupted. In that case, you need to repair the files and you will be good to go. We recommend you check our guide to know what to do if Windows Defender Firewall is not opening.
