Did you know that 75 percent of ATM machines still use Windows XP? Speaking of Windows XP, Microsoft will no longer support this 13-year-old operating system, even though it is the No. 2 operating system.

Okay, that is enough surprising statistics. Microsoft will not be providing any patches or updates against viruses. Many fear that this will make Windows XP machines open to hackers, and several feel that this is just a scare tactic.

I’m not certain what to think of that, and I am definitely running a later version of Windows on my laptop. Some computers that run Windows XP now might not have enough on the inside to handle later versions of Windows. So you could upgrade, if you can, or you could just start fresh with a new operating system.
