To activate the high performance/security mode, Please go to "HKEY_LOCAL_MACHINE\SYSTEM\Software\Comodo\Personal Firewall\AppCtrl", set the "OSMode" value to "3" and RESTART your PC.
Pls see post no.5 by rpsgc---- "We have added an experimental mode called HIGH PERFORMANCE MODE. In high performance mode, CPF operates much faster than normal mode (100% faster) and protection strength is much higher. This is one of the most important features to be tested. To activate the high performance/security mode, Please go to "HKEY_LOCAL_MACHINE\SYSTEM\Software\Comodo\Personal Firewall\AppCtrl", set the "OSMode" value to "3" and RESTART your PC."
This is the beta version (albeit quite solid program), we would love to hear feedback on this on our forums so that we can work on releasing it pls. thanks Melih
