Windows 10: 0x80070424 UPDATE ERROR, ANTIVIRUS GOT DELETED, AND FIREWALL GOT TURNED OFF

I bought a laptop a couple of months ago, and a month ago I got an update from Microsoft and installation got failed. sine then I am not getting any updates and showing 0x80070424system error. And not only that my Mcafee antivirus is not working since then. and then I tried to install Malwarebytes antivirus but it got failed. Windows security defender system is also not working since then. Im able to see Mcafee live safe and Microsoft windows update for windows 10 programs in control panel like below IMAGE. And somehow to installed quickheal antivirus and performed scanning but didn't showed any viruses. AND SINCE THEN MY LAPTOP BECAME VERY VERY VERY VERY SLOW

Good Antivirus + Firewall

I would never put anything Norton on my computer.

Nod32 is arguably the best antivirus. AVG is likely not as good, but it's free and at least pretty good.

Firewalls, I'd put Comodo and whatever "Tiny Personal Firewall" is named nowadays on your short list. I think Kerio might have sold it now and it's named something else. Otherwise, just put Comodo on your short list. I think the current version's ease of use has taken a step backwards, seems a bit counter-intuitive when trying to do certain things with it, but overall it does a good job and the price is right.

Error code 0x80070424 affecting Windows Update, Windows Defender and Windows Firewall

Hello

I got a new laptop a couple months ago and uninstalled the McAfee version that came with it and then disabled Windows Defender virus protection as these were causing several issues with programs that weren't infected.

Last update for my system was on 6-11-2018.

I noticed that there's some problem when I needed to change the App and Browser control setting for Windows Defender from Block to Warn as it was interfering with a game download on Steam. I tried changing the settings, clicked Yes on UAC prompt, but the
setting reverted to block when I changed to a different tab and checked again.

After this I tried using Windows Update to check for updates but I got the error code 0x80070424.

I can't change any settings relating to Windows Update, Defender, or Firewall. I can't check for updates. Update history and the Home page for Windows Defender are empty.

I tried a simple reboot. I have tried the sfc/scannow command. It found and fixed a broken file but the issue persists. I saw a thread suggesting downloads for registry files for Defender, Update and a couple other related services and then Starting them
from Services.msc and I have also tried that. I downloaded the free Avast antivirus and it deleted a winlogui.exe virus (which I found to be a trojan miner on Google).

The issue still remains. Please suggest steps for resolution!

Edit: The settings are all greyed out. On clicking on any link to additional

/advanced settings a UAC prompt pops up but nothing happens on clicking Yes.
