Q:
I have upgraded from CFP 3.0.x to CIS 3.5.x and now the GUI won’t start minimized.
A:
It seems like the GUI startup got registered twice in the registry.
Solution: start msconfig (Start, Run, msconfig [ENTER]).
Goto the Startup tab, Check if there are 2 Comodo Internet Security / Comodo Firewall entry’s trying to start.
Untick one of them press [APPLY] and restart. Now the problem should be gone.
