Well, back when I used windows TrueCrypt was still a thing.

Depending on your threat model, probably still TC though. If your threat model is the NSA, I'd advise you to not use windows anyways. Plus, if it does turn out TC has a major flaw, someone abusing it might make a noise. And as far as I'm aware the TC audit also hasn't found anything serious so far.

If you aren't betting your life on it, I think you're still fine with TrueCrypt, Plus, encrypting your full drive with it is something my mother could do. Next, next, next done, at least that's how I remember it.

Edit: Thinking about it, this is firstlook.org, maybe they know something we don't, but recommending BitLocker over TC sill seems like a stretch.
