Not sure if you're being sarcastic (there's the non-Nexus Android experience after all), but I did a fresh install of Windows 10 Pro on my gaming machine a while ago. Full retail license and an official .iso downloaded from Microsoft. There's barely anything installed on that machine, however I was also surprised to find Candy Crush in my start menu after a while. It's probably just a shortcut to the store, but it does look quite a bit like it's already installed.
by default windows 10 will show you 'suggested' apps in your start menu programs list. This can be disabled in the settings (just open settings and search for suggestions)
