Windows Defender encounters Error code 0x80070422

I had a prompt from my Windows Defender saying it's off, so I click on the link to turn it on but it gave me "Windows firewall can't change some of your settings Error code 0x80070422". Why is this happening? Any advice?

Hello,

Do you currently have a security software installed on your computer? What changes were made before this problem started? If you have a security software installed, try running a full system scan on your computer but make sure you update your security software’s virus definition before doing that. You can also try Microsoft’s safety scanner, this is the link:

Just download and install then run a full scan on your computer. You can also try and start windows firewall manually. Click on the windows button, type services and choose the option that has a gear icon beside it. Locate windows firewall, double click it and under the general tab, change the startup type to automatic.

Perform the following steps and I believe you will have a solution to your problem.

1. To check for any viruses in your system go for an online scan.

sc config wuauserv start= auto

sc config bits start= auto

sc config DcomLaunch start= auto

net stop wuauserv

net start wuauserv

net stop bits

net start bits

net start DcomLaunch

5. Go to ‘File’ then ‘Save as’ option.

6. In Save in box, select ‘All Files’ option and save the file named Repair.bat.

7. Right click on Repair.bat and Run as Administrator.

8. Now try to install the updates if successful delete the Repair.bat file.
