Cannot enable the Windows Firewall in Windows 7, error code 0x807042c

This is a short post for tonight. I was helping one of my customers fix their computer and it was infected with viruses. Yes, it was Windows 7 Home Premium and yes they had the User Account Control disabled! After cleaning up the machine, the Windows Firewall refused to start and presented error code 0x8007042c.

Here is a link to the fix:
