My Firewall and Microsoft Store on Windows 11 is so broken, 0x8007045B 0x80073D02, no paint or caculator or notepad app, can't install any apps from the store or use winget

Thanks for your suggestion anyway.

I have posted a detailed fix in the 7th reply.

But I don't think your reply is the best solution

as in place upgrade is no difference to that, this windows installation is so broken that I dont

even want to look at it. Lets just try to forget there's a problem, forget there's something wrong about the windows team, forget how bad the thing has became. Lets just try to do a refresh overwrite upgrade to see if there's magic gonna to happen to magically fix this broken windows

Following the suggestion in https://answers.microsoft.com/en-us/windows/forum/all/windows-defender-firewall-is-using-settings-that/914decb4-fbd9-451a-adfb-86e80adc1715 If the previous method did not work, try to initiate a rather simple registry tweak:

2) Change Firewall permissions

Press Windows key + R, type regedit, and press Enter.Navigate to the HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/BFE path.Right-click on BFE entry and select Permissions.Then click ADD and type Everyone.Click OK and then click on Everyone entry that you've just created.Mark the Full Control option under Permissions for Everyone.Finally, restart your PC.

Did this

3) Restore Firewall settings to default

Open Windows Search and type Firewall.Select Windows Defender Firewall entry and double-click it to open.Click the Restore defaults button positioned in the left pane.Finally, click on Restore defaults one more time to approve the choice.

Does not work

If this option did not work, try to reset Firewall via Command Prompt:

Right-click on Windows key and select Command Prompt (Admin).Alternatively, you can type Command Prompt in Windows search, right-click on it, and select Run as administrator.When the command line window opens, copy and paste the netsh firewall set opmode mode=ENABLE exceptions=enable command.Press Enter to execute and close Command Prompt.

netsh firewall set opmode mode=ENABLE exceptions=enable , this is a wrong command.

use netsh advfirewall reset instead, error 0x8007045B

C:\Windows\System32>netsh advfirewall reset

An error occurred while attempting to contact the Windows Defender Firewall service. Make sure that the service is running and try your request again.

C:\Windows\System32>netsh advfirewall reset

An unrecoverable Windows Defender Firewall error (0x8007045b) occurred.

PS C:\WINDOWS\system32> (New-Object -ComObject HNetCfg.FwPolicy2).RestoreLocalFirewallDefaults()

A system shutdown is in progress. (Exception from HRESULT: 0x8007045B)

Try to use Windows Defender Firewall with Advanced Security, says there's an error to load it with the snap-in

So there's no way to reset the broken firewall.

I believe I'm already on the latest version of windows 11. Does an in place upgrade of this would help?

Seems like a common issue and a lot of users got this error, especially users upgraded from Windows 10 to 11.

The other user's story

==============

While I'm glad to find out others have had the exact same issue, it's very frustrating that there's so few mentions of it everywhere I've searched. Something that worries me though (but may be purely coincidence) I also have an ASUS board. ROG STRIX B365-G*.Just to confirm it's the exact same issue: Upgraded from Windows 10 to 11 and everything was fine on the first boot. Next boot

• Settings > Windows Security > any setting produces error "You'll need a new app to open this windows defender link"(A repair reinstall or Win 11 followed by running Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage fixed this)
• Could access the settings now, but I still couldn't turn firewall on. "Windows Defender Firewall can't change some of your settings"
• System Event Log reports "The Windows Defender Firewall service terminated with the following service-specific error: The parameter is incorrect." Event 7024
• Windows Defender Firewall Service continually toggling between "Running" and "Starting". The services/drivers it depends upon like "Windows Defender Firewall Authorization Driver" are all ok though.
• The usual DISM and SFC fixes did nothing, but a repair reinstall of Windows 11 either from the ISO (tested 3 times both with and without Check for Updates selected) or from the online Installation Assistant (tested once) had the same result: Firewall after the upgrade, but broken after a reboot.

Eventually I gave up and disabled Defender Firewall in the registry and installed Avast One Free so at least I had a firewall and things like Steam Link etc would work.(But then a secondary issue of the Start Button breaking every time Windows Update ran and being unable to install Windows Terminal and other apps from the Microsoft Store. When I traced this back to the the firewall in an error state incorrectly reporting that the system was shutting down and the Store would immediately stop downloading/installing... I gave up.)So I'm back on Windows 10. *Just to check if it was hardware related though I took an image on Windows 11 before I blew it away and opened in Hyper-V and was still getting the exact same issues. Maybe next I'll open an image of my Win 10 in Hyper-V and perform and upgrade there and see what happens but I've spent so much time on this already.. It's a shame because apart from the firewall and Start button issues the rest of Windows 11 ran great on my hardware.

Mine system:

• Microsoft Defender Firewall is using settings that may make your device unsafe. Click Restore settings button, agree to UAC, but it does not do anyting, does not fix the firewall issue. Click Restore firewalls to default link on the bottom, click use recommended settings, reports 0x8007045B error**.**
• System Event Log reports "The Windows Defender Firewall service terminated with the following service-specific error: The parameter is incorrect." Event 7024
• Windows Defender Firewall Service continually toggling between "Running" and "Starting". The services/drivers it depends upon like "Windows Defender Firewall Authorization Driver" are all ok though.

Hi and thanks for reaching out. My name is Bernard a Windows fan like you. I'll be happy to help you out today.

I understand the issue you have, there is nothing to worry I am here to help since you have done basic troubleshooting steps and still having an issue, I suggest doing an in-place upgrade wherein it will upgrade the device to the latest version and repair all issues without deleting any files.
