body: In this question, I'm talking about the unsupported or discontinued software or the old versions of programs that are no available to buy on their official websites as there is already newer versions (e.g. MS Office 2007).
  
  
  I would like to crack those programs to be able to use them without buying them (which was illegal). Is that okay according to the US law?
