Microsoft has announced, to the dismay of many users, that they will be discontinuing support for Windows XP on April 8, 2014. The imminent discontinuation of support for the fabled operating system has drummed up a lot of questions from clients. There are various opinions on the subject, but I believe the article at the end of this post does a good job explaining what is happening, and some bad and better ways to handle the situation.
Keep in mind, if you are running XP in a business, I believe that you are at greater risk. Also, if you are running server 2003 or before, it may be wise to upgrade the server to at least 2008, or maybe make the move to the cloud.
