[Wapt] wapt-get command line local administrator

Hello, My name is Dominik and I'm glad I've found your Software. Been testing since 1 week and everything seems so good, thanks for that. My question: I figured out, that local administrators can install EVERYTHING with wapt-get command line. Even if packages Is set to "restricted" Selfservice Portal seems to work fine through. Any possibility to turn that off? Can I just delete wapt-get.exe after registration or any impact ? Thanks in advance. Grettings Dominik
