Windows Firewall won't start, error 0x8007042c

Looks good!

You had Comodo downloaded at one time. ( C:\Users\Ch\Downloads\cfw_installer_6106_53.exe)... did it ever get installed and work?

cherruc,

After you check out Jacee's question on Comodo, and, if you are still having the same issues as before, let's see if the following helps...

Please use the latest version of the Windows Repair (All In One) Download
Save to the Desktop

Right-click the tweaking.com program icon on the Desktop, and select: Run as Administrator
Click Next at the Setup, and follow the prompts.

Make sure to temporarily disable your AntiVirus program before the repairs are done.

At the program's console...

Go to Step 5 Backup, and under Registry Backup, select: Backup
Under System Restore click on: Create

Next, go to Repairs tab and click: Open Repairs

In the next prompt, press: Unselect all

Next, select the following entries: 1, 2, 3, 4, 6, 10, 14, 21, 26, and, 27

On the right side, check: Restart/Shutdown system when finished

Press: Start Repairs

When the program finishes, please restart the computer.

Please post Windows the Repair log in your reply.
It is located in the following folder:
64-bit systems - C:\Program Files (x86)\Tweaking.com\Windows Repair (All in One)\Logs

Also, please run the Farbar Service Scanner once again, and post the new FSS.txt in your reply.

Glad something worked for you!! :)

Is your Internet connection working OK?
