Its more of an educated guess, windows comes with firewalls, virusscanners, memory clogups, whatever, pure DOS is allways better, some users here already pointed that out. I'll have my friend do an update to 0711 from DOS and if he stops having the cold bug issue then there's some truth to it cuz he already tried flashing from asus windows update and he's still got the cold boot bug. Will report back when he has flashed with AFUDOS.
