Question What's happened to Windows Defender, my security, and Ethernet? And how can these be fixed?

Hi

I'm currently having a strange problem related to my firewall, Ethernet connection, and security. I'm sure they're linked. Basically, I'm unable to add exclusions to Windows Defender and I get this message:



I'm not even able to turn off Real-time Protection either. Then, when I tried briefly disabling my Ethernet connection via Network Connections, I get this error:



I'm not even able to check the Properties either.



I've tried following the suggestion linked here - https://answers.microsoft.com/en-us...nnection/35908048-559e-4339-9c60-405fc3896178 - and I've tried disabling and uninstalling the drivers for the adapter via the Device Manager and restarting. Problem remains. 🙁

To add to this, I'm not even able to edit permissions. Whenever I go to the Security tab of a file/folder, and try to edit a user or group, I get this pop up:



Any ideas/suggestions? I'm totally stuck with this and I don't know what to do/try. 🙁

Thanks

If that doesn't work and the issue cropped up mysteriously after an OS update, try and perform a system restore

Hey. Sorry, I didn't even get any notification you replied. Not via email or on here. :-\ I'll bookmark the video for future reference.

Looks like I've managed to sort the issues out. All thanks to the awesome Windows 10 Manager tool. I need to make use of it more often! 😀 I'm not sure which one it was, but I went through all of the fixes in turn, rebooted, and all three of those issues are gone. And the UAC is at default, too. Success!

EDIT: Just took a peek at the video and I actually used that myself. It did do the trick, but it disables UAC, which isn't good really. But it was fine as a temporary solution/to troubleshoot.
