Right but windows also aims to be backwards compatible which means it was trying to run things designed for a single user system undermining protections.

That makes absolutely no sense.

'vim' wasn't designed for multi-user use. Nor was emacs.

Applications don't need to somehow be "designed" for multi-user systems. It's up to the underlying system to enforce application isolation in various ways, which NT has and does.
