Am I able to reuse PC game activation codes?

Ok I am completely new to PC gaming. Am I able to reuse the 25 alphanumeric game activation code that comes with every PC game (usually located either on the back of the game's manual or on a label inside the case) which you input during the installation? As in, use it on an entirely different PC?

most of the time no.. its 1 shot dealio

certain titles have installation limits like red alert 3 for example had a 3 pc activation limit.

Sometimes yes, but more than not no

So what are they tied down to exactly? The HDD? If I change the HDD will reinstalling the game and reusing the same activation code not work?
