On the Internet, search for "apps and programs to run games in windowed mode" to find several programs that can be used to play games in windowed more or in fullscreen mode. Some of them are free, and some have to be purchased.

Try different settings on different games. Some games will allow you to use launch commands, some won't, and some launch commands will work in some games and some will work in other games. For this reason, it's important to try different things on different games and keep all of these possibilities in mind, to be able to play in borderless, windowed, or in fullscreen mode.
