Okey, so... Today I was debugging a few programs and found out some few cool things I havent checked out...
Theres program X (It can be anything) and I opened it up into PE Explorer to copy resources... Oh boy, theres a "Dialog" section. I opened it up and I see list of Dialog files numbered from 200 to 240.
I opened "213" which contained "Insert Serial Number" box. I deleted the dialog and saved the .exe file.
Oh maannn... It really worked! xD
It now skips the 'Enter Serial' screen. Trolol
