Windows XP is still installed on 37 percent of computers worldwide. When the OS will lose its support in April 2014, it will then stop receiving security updates and will quickly deteriorate into an easy target for even inexperienced attackers. Wolfgang Kandek, CTO of Qualys, said in a blog post that Windows XP is very likely to become an easy target for hackers in less than 9 months!
Now it's your duty to help your friends and relatives to upgrade to Windows 8 or introduce them to Ubuntu.
