on start up windows keeps ballooning a message that I have no firewall. CIS firewall appears to be working. How can I be sure it is? If it is working properly, how can I be rid of irritating message?
Try the Security Center reset. Does that do the trick for you?
Open a command prompt by clicking Start → Run. Type cmd and click OK.
In the command prompt window, type NET STOP WINMGMT /Y and press ENTER.
Type REN %WINDIR%\SYSTEM32\WBEM\REPOSITORY REP.OLD and press ENTER.
Type EXIT and press ENTER to close the window.
Restart the system. Windows should start normally, but you may be prompted to restart the system once more to complete the changes caused by resetting the core repository. You may also need to restart once more if Windows Security Center still does not detect your security product.
