How to upgrade a Python installation on Windows 10?

Question

I have Python 2.7.11 installed on one of my LAB stations. I would like to upgrade Python to at least 3.5.

How should I do it? Should I completely remove the program 2.7.11 and install a new one? Is there any way to update it? Is updating a good idea?
