Unfortunately, the option to change this is missing from 3.10. But, it is still in 3.9, if that is what you're using. If it's 3.9, open CIS and go to Miscellaneous - Settings - General tab. If the option is checked, uncheck it & hit OK. Go back into Settings - General tab, recheck the option & hit OK. This should have created the startup correctly, which should read..
"C:\Program Files\COMODO\COMODO Internet Security\cfp.exe" -h
If you have CIS 3.10, it will be a little more involved.
