In 90 days, on April 8, 2014 Microsoft will end extended support for Windows XP. This means that no additional security patches, bug fixes, or service packs will be released and that users will no longer have access to free or paid technical support. Systems running XP won’t suddenly stop working on April 8, but they will become increasingly vulnerable and the source of additional problems to your company. I doubt you have called Microsoft for XP support for years, so why is this a big deal?
