Next thing to try: Windows Linux Subsystem.

Can it replace Cygwin?

Does it integrate nicely with win ntfs / apps?

[Summary from the FAQ] ⇒ Provides a bash shell and /mnt access to the win fs. Does not provide GUI support. Mentions apt-get (with potential errors due to a lack of udev).

I should also (re)learn Powershell (again and/or for real) and take cheat notes on how to be proficient / use it.
