The latest Fast Ring Insider Preview build of Windows 10 (14316) includes the new Windows Subsystem for Linux (WSL) that Microsoft announced at their Build conference last week. I have to admit, I kind of enjoy being able to open a bash prompt on my PC and using Linux commands to interact with the file system, use vi to edit files (yes, I use vi!), and running shell scripts. I haven’t had a lot of time to use it in-depth but it will be interesting to see what kind of cool stuff can be done with this.
