If you are still using a computer that runs on Microsoft Windows XP (eXPerience) operating system, it is better you throw it away or upgrade to Windows 8 or stop using it to surf the web. Microsoft on April 8 will ''officially'' kill and bury the old operating system. That means the company will stop updating it. And that happens, if you are still using an XP computer, you would be expose to hackers and viruses. But, you can still use it with no harm if only you stay offline.
