Some updates are intelligent and they first check your machine to see if the chips and firmware can handle the update. I had Flash tell me I can't update on my computer. What some of the system updates don't tell you is that you will need 4 more megs of ram to operate it. You would think that would be automatic, but it's not. If you google it you find loads of stories of bad updates and then... try to go backward with an update. Impossible. I'm sorry, I learned a few of these lessons the hard way and yes, if you have a new computer and it offers you an update for Word, why not.

That's why often there's updates to updates, simply because they screwed up. My bank software handles my on line security and not my Yahoo browser. In the last year I met some really young people at a coffee shop and they helped me with my Android tablet and if they want, they can crack anything. Sony wasn't cracked for money, it was cracked as a trophy and they can do it easily and that includes your banking info. Fortunately most of these computer guinness aren't criminals they just love to play with the big corporate systems like learning to roll backward with one hand.
