Does Microsoft REALLY care?
A quote from the article states, "Anyone connecting a Windows XP computer to the Internet after Microsoft drops its support in April 2014 is not only putting themselves at risk, but also endangering all of us on the Internet -- as their computers may be hijacked into botnets and used to spread malware and spam attacks."
Well, if Microsoft REALLY cared about the Internet getting flooded with a bunch of compromised XP machines doing denial of service and other sorts of mischief, they'd offer everyone running XP a nearly FREE upgrade to Windows 7 Home Premium. It isn't like they'd be losing money doing so.
Why Windows 7? Because most XP machines still running could fairly easily run Windows 7, but NOT Windows 8.1 because it requires a motherboard with a BIOS supporting a feature called Data Execution Prevention. Throwing 500 million perfectly good PCs into the landfill ought to be a crime, so giving an upgrade would be a good solution for many of them.
I set my neighbor up on Ubuntu (an easy to use flavor of Linux) and after about 20 minutes of instruction she was good to go. At least she will not have to buy a new PC just to do things she was already doing. Linux is not just for geeks only these days.
