I liked the quip of how computer operating systems are like cars. I wholeheartedly agree, because the next one is generally superior to all those that came before it. I'm sure this won't be a popular opinion in these forums....
The point of not convincing others of differing strongly held beliefs is valid though. Seems to be a human condition to dislike anything new/different and ignore any other information no matter how valid it is.
I still vividly recall when people changed from XP to Win 7. I used to be the "go to" guy for about 6 friends whenever their computer had issues. A couple of them would call about 3-4 times a year. Since they all got on Win 7, I almost never hear from them. XP was vastly better than what came before it, but I'm glad that is gone!
For Vacbear58, no idea why you can't use the upgrade assistant for free. Perhaps your it is due to your location or the Win 7 license you are trying to upgrade. I've now upgraded 4 different Win 7 computers and never incurred a charge for any of them.
