Error code 0x80070422 Can't turn on firewall

I just installed the Windows 7 upgrade. Now I have problems with the firewall. It is prompting me that the firewall in not turned on & prompts me to use the recommended settings. When I click on this the message "Windows firewall can't change some of your settings Error code 0x80070422". I get the same message when trying to turn on Windows Defender. I used Mcafee virus scan plus (with firewall) before with no problems.

Prior to installing the update, I removed Mcafee Virus scan plus & related Mcafee software. After the upgrade & finding that I had no firewall, I reinstalled Mcafee (with firewall). The firewall for this also does not work. It can't recommed a fix.

I was experiencing the same.

My personal firewall with mcafee, then tried the windows firewall.  Same issue, unable to turn on.  Firewall gave me: 0x80070422 error.

I tried this:

in windows vista, I go to start > typed in services & launched that window that has a mechanical wheel.  I found windows firewall, double clicked.  Selected under the general tab: automatic in the startup type, then it enabled me to select start.

Windows firewall was restored without an error anymore.  I then proceeded to activate the mcaffee, & it worked as well.  I use mcaffee personal firewall.
