How is subcomponent blocking done in Version 3?
CFP 3 will only block .exe files, but if you want alerts for DLLs (you'll get A LOT), go to Defense+>Advanced->Image Execution Control Settings->Files To Check, then Add->Browse... and type *.dll, then click the + and Apply.
Also, is there still a method to block all outgoing connections during Windows bootup?
Don't think so. Might be some, but I can't think of any.
