Hi, I need some help.
I know that I must not have 02 Firewalls working at same time in one PC.

After I install Comodo Firewall in Windows 7, XP, Vista, its native firewall has been automatically disabled.
But after I installed Comodo Firewall in Windows 8.1 its native firewall keep active.
So what should I do?
Should I let Comodo Firewall and native Windows 8.1 Firewall working together?
Or Should I by myself turn off Windows 8.1 firewall?

You should turn off the Windows firewall (via Control Panel, Windows Firewall, Turn Windows Firewall On or Off)
