I dont think that you friend or dad was lying
One of my friend who worked for microsoft told me abou tthe password too
( When i ask him to tell me the password he said no) but he gave me some
information he said its a 25 character password and ( its not the windows key) he also said Microsoft his monitoring the internet to see if anyone posted the info to delete it. So i think this password exist and they do not want us to know it
so keep searching and dont post it when you find it
