I am running Windows 7 Ultimate 64bit, now when i go to Control Panel and then to Windows Firewall I notice that it is turned off with box saying " update your Firewall settings " use "recommended settings " so I click on it and then I get a message coming up saying " WINDOWS FIREWALL CAN'T CHANGE SOME OF YOUR SETTINGS. ERROR CODE - 0x80070424 " so I have no idea what I can do to get the firewall working properly so am hoping someone can please help me, Thank You
