Yes, you can install Windows on the machine, providing that you have a copy of Windows.
Yes, there is a way to bypass the login on a linux system. However, if you know nothing about the system, then none of what I would tell you to do would make any sense at all. And one of our rules at BC is that we do not discuss bypassing security measures. We have no way of knowing whether or not you really do own a second hand laptop with linux installed, or if you are really trying to get into a system that doesn't belong to you. Really though, there are hundreds of sites that tell you how to do it.... we just are not one of them. Sorry.
I'll leave the "linux different that windows' discussion for someone else, but it has already been discussed quite a few times on here, and poking around the linux forum here might answer some of your questions.
