Windows 7: Windows Firewall won't start, error 0x8007042c

Windows Firewall won't start, error 0x8007042c

Windows Firewall won't start, getting error code 0x8007042c. BFE won't start, error 5: access is denied. I've scanned for viruses using Malwarebytes and nothing showed up. I tried downloading and adding the registry files again as suggested in some other threads, but that didn't work. I tried following the instructions in this thread for fixing the BFE, and after running

REG QUERY "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\S-1-5-18" /S

I got "ERROR: The system was unable to find the specified registry key or value". The other commands returned normal results.

SFC /scannow returned corrupted files "" & "telemetry.ASM-WindowsDefault.json" but this was fixed with The Tech Cookbook fix - The Tech Cookbook – Windows 7 update (KB3022345) causing corrupt files.

A few weeks ago my Network Diagnostic Service sometimes would not be running either, but that just stopped happening so I'm not sure what caused it or what fixed it.

Have you tried going to a previous Restore Point at a time when this issue was not happening?
System Restore

If no joy, try uninstalling AVG 2015, and then try to start the Windows Firewall.

Also, please use the SecurityCheck Download
Save to your Desktop.
Double-click: SecurityCheck.exe
Follow the onscreen instructions inside the black box.

When done, a Notepad report opens automatically, called: checkup.txt

Please post the checkup.txt in your reply, but, do not take any corrective actions!

There were no system restore points before this issue started happening. Even when I tried to restore to an earlier point, I got an error saying that it was unable to be completed because it couldn't access a certain file, if I remember correctly. Now there are no system restore points.

I tried uninstalling AVG 2015 and starting Windows Firewall, with no luck. I removed AVG with the AVG remover because when I tried to uninstall it through Control Panel it would fail partway through. I also cannot reinstall AVG or other antivirus programs atm.

Please find attached checkup.txt. Thanks for your help!

Please press the Windows key and the R Key at the same time.

In the Run box, type: notepad

Copy/paste the entire contents of the codebox below into notepad:

@echo off

sc qc winmgmt
notepad look.txt
del &0
Now in Notepad, go to: File > Save as
In the Save as line type in: wmi.bat
Change the Save as type to: All Files (*.*)
Press Save, and do so to the Desktop!!

Double-click the wmi.bat file to run it.
A Notepad report appears on the Desktop.

Please post its contents in your reply.

When I ran the file, the cmd window reported "System error 5 has occurred. Access is denied."
This is what appeared in the Notepad report:
