Prior to routine pained calls from many ancient cousins, I tried this on the 5 elderly sample machines here. 3 successes, 2 bluescreens without damage, worked on restart. (Why does it always download the whole lot again?) Classic Shell recovered with one click on each, preferred XP-style desktop was unaffected. Spybot anti-beacon found only one reversion, but OOshutup found plenty to do. Claimed 'improvements' have no impact at all on geriatrics' use-case, but we should compliment Microsoft for not breaking anything. Oh yes - 'Fall' to those of us who were educated on Milton's 'Paradise Lost' suggests the very Devil's work - can't they look at language settings and substitute Autumn?
