Some Windows 10 versions have Windows Subsystem for Linux.   Once you
enable this (if available on your version) you can choose from several
linux distros.  You get a command-line environment (for GUI app's you use a
Windows X11 server).  There is limited networking and disk IO is slower
than bare metal.  If you are running small batch processing jobs it may be
faster than rebooting.  The linux system lives in a special directory that
contains a standard linux layout (/usr/bin, /home, etc) so you WSL home  is
not the Windows %USERPROFILE% directory and therehave been warnings that
you can encounter problems trying to manipulate the Windows filesystem from
WSL.  There are also some limitations on things like stack size that only
documented via blog posts.

In my past I have run workshops using linux software using VM's installed
on the teaching lab's Windows boxes.   Once we got past the installation,
these VM's were quite practical for small projects, but not at all suited
to "real" tasks with large data sets.  I have tested a bunch of the same
linux programs under WSL to see if it would be possible to avoid installing
the VM and linux.  Most ran fine, some need tricks to increase stack size,
and some won't run.  Most standard distro packages that don't do network
I/O install and run well.

In my experience, 4G B ram was just enough, using a basic linux window
system on a Ubuntu 12.04.    I've noticed that recent distros have
increased the minimum RAM requirement, so you have problems booting into a
linux GUI.
