I remember this from my Windows XP days (spent another two years on Win 7, before switching to and being happier with Linux). No interest beyond nostalgia but indeed here I am reading at least the comment thread :). Gotta agree that I'd also not use it for anything serious, like it's perhaps useful as hardening for your browser because no regular exploit will expect it, but that's about it. I was already weary of it with my limited security knowledge back in the teen days, and reading of someone whose browser password was stolen, I'm happy that I didn't trust the claims that I seem to remember it making back then. It's a bit similar to containers I guess: probably even safer but even as a security person I don't trust myself to configure those malware-proof.
