The first sentence says it all: it is _not_ available in all of the versions after Windows XP. Combining that with the fact that it is not open source and it is not cross-platform, it's basically useless to me.
For now on, I'm sticking with TrueCrypt 7.1a version which I downloaded from https://truecrypt.ch/ on all of my machines.
So, an open-source product which the developers have publicly declared as insecure, and on which a major code-audit has stalled inconclusively, is superior to closed-source _how_, exactly?
Not saying you're wrong, per se, just that it seems like all the choices are wrong, here.
