Stopping someone from using it - no.
Stopping someone from clamming it is their code - maybe.

If your program is compiled into an exe file, you can examine the hexadecimal
code using debug.exe. So far as I know every Microsoft operating system has
the file buried somewhere within the system. You can use that program to
examine the hex code of the compiled program. There may be places where the
code is 'just taking up space'. If so you can replace some of that code with
your name and date. It will never show when the program is run so there is a
chance that a thief will not look for it. It's been so long sine I used debug
I don't remember if you have to use hexadecimal to input your name or if you
can simply use letters.

Somewhere there is a program named Abacus. It will tell you what every hex
statements does, in raw computer language.
