I can't find windows defender in regedit

I can't find Windows Defender in regedit.

Under HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender

it only shows

• Policies
• Microsoft
• Cryptography
• Peernet
• System Certificates
• Windows
• Windows NT

Next should come Windows Defender but it is not there. I am trying to fix Error code - 0x800705b4.

0x800705b4 : This error code will happen in windows defender if any third party antivirus or firewall disabled your windows defender temporarily.

Browse registry again after disabling the third party antivirus

Step 1

If you have any third party antivirus software and firewall disable them temporarily and make sure that the Windows Firewall is turned on. Then check if the issue reappears.

Step 2

1. Open Run, and type in services.msc then press Enter.

2. In services window, locate Windows Defender service in the services list.

3. Verify that the Status is Started. If the Status column is blank, right click on the service and select Start.

4 If you get error trying to force start the Windows Defender service, try to change the Startup Type to Automatic, and then restart the computer.
