I'm running Windows 10 Insider Preview in my machine to give it a go and get used to it before general availability. One of the things that I find annoying is that it seems to preload modern (universal?) apps for them to open faster should you decide to use them probably.
For example, in the following screenshot of a task manager you can see 4 applications being preloaded (sort of opened, but suspended and not shown in the taskbar or any other place) which are the ones in grey. They were not even opened in that Windows session:
I'd like to know if there's a way to disable this functionality.
