100% legally are hard.

In principle, you must enquire about every "piece" or 
"package" (an entity that has an entry http://ctan.org/pkg/..., 
or what has a line in the MiKTeX Package Manager, alternatively 


) you are using what license it has.

For CTAN packages such as "txfonts", you find the license

If anything you use apart from direct Microsoft software
comes from MiKTeX, you can get about 99%% from


where Christian Schenk starts "To the best of my knowledge,
all software in this distribution is freely redistributable".
(Alas, that is 2017 ...)
