With Windows 10 you can install the Windows Subsystem for Linux (WSL). This is basically Ubuntu Linux (one of the most popular versions of Linux) integrated into Windows 10 in a way that command-line Linux programs can be executed easily. News and announcements can be fouund at https://msdn.microsoft.com/commandline/wsl/about (msdn.microsoft.com/commandline/wsl/about). Michael Doob reports on 2016-06-01 and 2017-02-03 that this works quite well for the programs necessary to author with MathBook XML.
Ubuntu Linux installs new programs using apt via a command such as:
rob@lava:~$ apt-get install xsltproc
Possibly you will need to prefix the above with sudo to gain the right privileges to install new software.
This short description is far from complete, so feel free to contribute more details. But Ubuntu and WSL should be well-documented on the Internet, so this should be enough to get you started.
