The coa usually goes with the installation ID which changes every installation...... my advice... try to see if there is a recovery parition usually you can press one of the F keys, it will tell you at start up for recovery parition. Other than that..besides downloading it, or buying it from..a website there are no other options.. install linux.. ubuntu.org (open source OS).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
