Halo Wars 2 Installation Media

Is there a simple way to save the Windows Store download of Halo Wars 2 (36GB+) so that I can reinstall it at a later time? I have a data cap of 250GB per month with my ISP. When I need to reinstall the game it will download the entire 36GB+ installation all over again and it uses a significant portion of my monthly data allowance. I would really like to be able to create Halo Wars 2 installation media on a 64GB+ USB flash drive so that I don’t have to re-download the same installation files every time I need to Refresh or Reset my PC.

If you have the Windows 10 Creators Update installed I don’t think you can move the folders anymore.
