You're way too late:

I agree.
Me too, but you can't say anything about what other people believe or are made to believe.
Later Windows are horrid by comparison with XP and won't run the applications that I enjoy using or need to use.
Have you tried to run/install the applications in compatibility mode? Have you installed all VisualC++ runtime packages, DirectX9 and other stuff?
I'm too set in my ways I guess but after having used XP for 13 years and not havng yet suffered from any effects of malware or similar attack, I must be doing something right.
You might be a part of a botnet and you wouldn't know it. You could be compromised by a cute kitty picture or an ad on your favorite's blog and you wouldn't know it. Getting malware only from downloading stuff and opening mail attachments is way too outdated information, having only malware which actively shows itself as such and tries to destroy/sabotage your computer, too.
Again, we're living in 2014 and not in 2004 when Sasser came around.
Wait until network connected clinical support systems running critical custom specialised software start misbehaving and costing lives.
Network connection is not equal to internet connection. Even if they would have run with Windows 8.1 or with Linux, it would be still way to risky to let them run with internet access. Those specialized machines rather run in a separated, secured network.
Aside from that, if they have Microsoft XP embedded, they would still get security updates for about 3 years.
