Microsoft’s support for two major products ended on Tuesday: Windows XP and Office 2003. As a result, the company will no longer release security updates for either of the two, and it recommends users who still use either to get a newer version. If you’re wondering why April 8, 2014 is the date support for both of these products ends, it’s really quite simple. Microsoft releases regular patches on Patch Tuesday, the second Tuesday of every month. Microsoft supports its products for many years, and depending on when service packs as well as successors are released, the company eventually announces, in advance, when it will cut off support. April 8 happens to be the last Patch Tuesday for both products, meaning if security holes are found after April 8, they won’t be plugged.
