How to uninstall SW properly so that I can use it in another machine?

Hi, I have SW Student 2018-19 installed on a laptop computer. I am returning it to the manufacturer due to product dissatisfaction. If I reall correctly, if I just uninstall the software from control panel, I will not be able to use it on another machine since I need to do some kind of deactivation? Am I correct? What is the proper way to uninstall the software so that I can use it on another machine? During the time between deactivation of one machine and activation on another machine, do those days count as part of the 1-year use?
