Anniversary Update for Windows 10 has been finally released.
You can wait for it to come with Windows Updates, or (like I did) grab it from here as a standalone executable and install it manually.
Like I anticipated in my previous post Windows 10 to include Bash. Should you care? I don't, Windows 10 will include a Linux subsystem that allows to run Bash commands directly in Windows.
I already voiced my personal opinion on how irrelevant this is to myself personally, as well as to most UNIX/Linux users. However, it's a very exciting feature to test and it can result to be useful in some specific occasions.
Prep steps & installation
After installing the Anniversary Update, you'll need to enable Windows Linux Subsystem.
