You can, it is easy to do, but it is illegal (reverse engineering
commercial software is illegal, and may have DMCA implications depending
on the offense). Why not pay the person/company that took the time to
write the software? If money is the issue, poke around, I am sure there is
something free/shareware that does what you want. If you are just curious
how this is done, and don't plan to use this information incorrectly, take
a look at "Hacker Disassembling Uncovered," and chapter five in "Hack Proofing
Your Network."  I am not in any way shape or form condoning software piracy.
These are great resources for seeing how pirates break copy protection, and
can be very valuable resources for protecting the software YOU spent your
time and money to write.
