Two months ago, Microsoft announced that Ubuntu, Fedora, and Suse would be available from the Windows Store. Just a few days ago Ubuntu was the first to become available. Instead of a dualboot, Ubuntu runs sanboxed parallel to Windows 10. Currently this feature is only available to Windows 10 Insiders, but will be made public in September or October of 2017.
I have not decided if I find this to be a 'good' or 'bad' thing at this point. For now, it is 'interesting.'

This has been buried deep in windows 10 for a while now, if you knew where to look, it has been made more public via the store.
Good way to have a LAMP stack on Windows 10 for test deploys. And easy to blow away and rebuild when needed, so good tool for the right use cases.
Also a unix style shell has far more powerful commands for file manipulation than command prompt :)
