April 8, 2014 is the last date that security updates will be published for Windows XP SP3. After that date, it will be officially unsupported by Microsoft. ITS is encouraging those still using Windows XP to upgrade to a supported operating system (ie: Windows Vista, 7 or 8/8.1) before that date. Microsoft has provided a tool that will identify if you are running Windows XP, and, if so, it will provide some options to upgrade the computer to a newer and supported operating system. The tool can be found at the following URL: http://www.amirunningxp.com.
