Hello, I have pretty fast internet, 150Mbps download and 100Mbps upload. I bought Gears of War 4 for Windows 10 and decided to "preload" it since it's 86Gb and even on 150Mbps fiber line it would take some time. Thing is, Windows Store app hogs all bandwidth, slowing streaming and web browsing on my computer and network as a whole to a crawl.
To be specific, it maintains 142-148Mbps download speed on network according to Task Manager. So it's impossible to watch YouTube, Twitch or any other streaming service. Other software obeys QoS scheduler built into Windows usually even without any bandwidth settings and doesn't interrupt VoIP, Streaming and Web Surfing. Yet Win10 Store app just eats up all available bandwidth my internet can provide and puts its traffic as a priority one over streaming services and web.
Steam for example has setting that allows you to limit bandwidth (say to 100Mbps or any custom number), that is on top of not prioritizing its own traffic. I looked everywhere and there is no such option for Win10 Store app, so I either have to put my purchase on download and do something else while it takes time to download, since it's impossible to watch streaming services or even surf the web comfortably.
