What actually happens when you delete System32? All I know is that it contains system files. Would it even affect a 64-bit system? Or am I misconstruing what the 32 means in this context? On a somewhat related note, is 128-bit computing practical, likely, or close at hand?

i have *no* idea. i use windows maybe a handful of times a week which entails booting my windows partition and immediately opening steam and playing some dumb game with friends & nothing else
