When you buy a morning education machine, the general merchants will tell you the password, and you will activate it directly after you buy it. Don't worry, the merchant will activate the installation for you, and you can buy it boldly.
There are two main types of activation codes: one is the activation code for general software, and the other is the activation code for games. Some software will add password programs and use activation codes in order to make their software face a specific paying crowd. Only by entering the correct password can you use this software normally.
