Windows xp no more security patches

If you haven't rebooted in 6 years why would you be sorry they stopped support?
You haven't updated in all those years so why start now? :)

If it were for me I would limit all old Windows-versions and their botnet-invested crap from the internet. That would safe the world a lot of energy now being wasted fighting automated spam and hack-attempts coming from botnets.

Just the Desktop (Home/Personal) hasn't been turned off/rebooted in years. The Business computers have been rebooted periodically and were kept updated. Some of the stuff in the shop requires software that won't work on newer Operating Systems (like the software for one of my Scan Tools). The same kind of situation that MobileCustoms mentioned too.

I forgot, I have a 4th computer running XP (XP Media Center Edition). An older Laptop (circa 2008) that I use as my Media/Home Theater center. It's wired into my home theater system.
