How can I get another activation code without paying for another CD?[/al_question]
If you’ve legitimately lost your activation code, you may be able to get assistance from Microsoft by calling them. This applies to both Windows and Office (the questioner didn’t specify.) But you must have a legitimate copy of the product in order to do so.
It’s possible that if you’re unable to prove you have a legitimate copy you may not be able to get a new activation code, but I’m not sure exactly what kinds of proof they might require so do give them a try.
The lesson? Don’t lose the code.
