If you had automatic update turned on at the beginning of October, you got clobbered with a bug-infested, out-of-band update for an IE-related zero-day that never appeared in real life.
Later in the month, those with automatic update turned on were treated to a wide assortment of bugs (Start and Search fails, RDP redlines, older Visual Basic program blasts) & only some of which were solved with the month final, optional, non-security patches.
