Microsoft will stop support and security patching for Windows XP on April 8, 2014. The international security community believes that Windows XP computers will be heavily targeted by organized crime and hackers as soon as Microsoft ends support. We strongly recommend that you migrate to a supported Windows platform, such as Windows 7 or Windows 8, before the end of March 2014.
Microsoft periodically releases security patches for Windows operating systems. Downloading and installing these updates will help protect your computer from viruses and threats.
