It’s been two years since Microsoft stopped supporting Windows XP, meaning if you’re still running it and malware writers find a way to attack you, you’re on your own. And despite the fact that it was launched in 2001, there are still people running Windows XP (a few of them in government departments that should know better).
Depending on whose measurements you believe, Windows 7 didn’t overtake Windows XP as the most widely used version of Windows until 2011 or even the middle of 2012; even in 2014, you could still find it on as many as a third of all PCs around the world. Different tracking services show different numbers, but whoever is measuring, XP is the OS that won’t quit.
Businesses – and home users – who didn’t want to replace PCs that were doing what they needed to do, even for the improvements of a new OS. Then there are the gamers who need it for compatibility. For years, South Koreans had to stick with XP to run IE 6 for the ActiveX plugin that was the only way to shop online.
