Windows XP is a 7 year old operating system. Microsoft ads on TV tell us that we should move to Vista. They put a deadline in place. According to Devil Mountain Software and a few others, more than one third of Windows systems are still being downgraded to XP though. What more can Microsoft do? Well, the deadline of January 31st to stop allowing OEM manufacturers to sell XP has been extended. You will now be able to purchase Vista and then have a downgrade option through to July of 2009, at which point XP will be well over 8 years old. Pundits say Vista sales are up, but really it makes you wonder how much of that is actually software being immediately downgraded back to XP. Is it possible that Vista is the worse disappointment in Microsoft’s storied history? Will corporations ever truly trust Vista?
