How to Install Composer on Windows 7/8/10

I am a YouTuber and I also do niche marketing. In the process of create my niche blog using WordPress, Drupal, and GatsbyJS, I learned a few things like html, css, JS, CMS, MVC frameworks, C++, Python, Ruby, MySQL, Windows and Linux. After some time.. I realized that I can share my knowledge with people on YouTube and through my blog. So, here I am. You can ask me if you have any question about these technologies.
Thanks,
