Of course it is. but many people don't know that, and they're popping up all over the place asking how they can recover their data. MS mitigated this somewhat by providing a 30-day rollback mechanism but that was not enough for some people - the damage had already been done. None of this impacted me, other than my little waste of 2-3 hours on a Saturday night described in post # 18 - actually not a waste since I learned a lesson. I certainly wouldn't have taken it on without having full disk images of 3 varieties of both laptops but there really are people without a clue and a limit to their patience. I want to say you merely have to RTFM but sometimes the right manual is hard to locate for some folks.
