Typing different languages on Windows can be a pain. In undergrad, I memorized all of the relevant alt-codes for French characters. When I started studying Sanskrit, my professor shared this US International keyboard from Carleton College. It has covered almost all of my accent mark typing needs (outside of IPA characters), and is very intuitive to use for someone who grew up with a standard QWERTY US keyboard.
