Hey, just so you know ... this post is now about 7 years and 11 months old. Please keep that in mind as it very well may contain broken links and/or outdated information.
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.
Now that the Creators Update is out, the WSL has been updated to use Ubuntu 16.04 (instead of 14.04 that it originally installed). You can use these instructions to upgrade your WSL.
