If you have a copy of Windows Education, it will continue to function after you graduate, but it will eventually lose its activation. In addition, you may have difficulty accessing any data of yours that is stored on your school's network, and may lose access to apps that are owned by your school.
For the best, problem-free experience, if you are keeping your school computer, do this:
