I upgraded from Windows 10 to Windows 11 via Window System Update today, and everything seemed to go fine, except when I found that none of my programs that I use to remote into my PC from my phone worked anymore. I was wracking my brain trying to figure out why this was, and I finally realized that Windows Defender Firewall isn't working at all anymore. Depending upon where I try to look at Windows Defender Firewall's settings to toggle it off and on again, I'll get errors like, "A system shutdown is in progress," or "Windows Defender Firewall can't change some of your settings. If I go into the Services tab of the Task Manager, mpssvc, the Firewall service, is also constantly flickering between Running and Stopped.

I was able to fix it after doing a full system repair with the Windows 11 .iso from Microsoft, but it broke itself again after restarting the machine, giving me the exact same errors. Installing a third-party firewall didn't work, either.

I've tried restarting Windows in Safe Mode, but that didn't fix anything, and I tried at least one tool downloaded from the internet to run a fix on Firewall specifically, but it didn't work. I even went into the Microsoft Store to try to redownload Firewall, but it told me that there was an error even there. I've tried everything I can think of, and I'm at the end of my rope here; any help would be immensely appreciated.

After trying everything I could think of and every solution that people had online to the errors that I was getting, I ended up backing up my important files and doing a full reinstallation of Windows 11, and everything works now. I don't know what happened with that initial upgrade, and I don't think I'll ever find out.

I have the same sorts of issues with one of my computers. One thing i have noticed with other similar issues by others, nearly all of them have an asus motherboard. and I see you have an asus motherboard. My question is since you did clean installation, have you have any issues with the defender firewall. After you did a restart the firewall still works properly?

Thanks
