[how to find reg. key from registry editor.]

I'm not really sure what you're asking. Why would you want to delete a serial number you wanted to add?

I mean using the portable application without writing anything outside. similarly like running the application from usb drive on workplace computer & can exit the program without leaving any traces on the computer.

regedit /s serial.reg

great thanks, is it possible to delete the serial.reg from registry upon exiting/close the program?
