While Microsoft has, understandably, reminded the general public for years that its support and updates for Windows XP will end on April 8th, there is another software product that will soon stop getting patches after that deadline is reached: Office 2003.

Today, Microsoft has a new post on its Office blog, along with a humorous infographic that shows how much the computing world in general has changed in the past decade since the launch of Office 2003 in August 2003. While the software had a number of interesting features, including the first version of OneNote and the final version of “Clippy”, Microsoft now says that individuals and businesses who are still using the software now need to move on. 

Naturally, the company would prefer users switch to their Office 365 subscription service. The blog states, “…. you’ll never have to worry about outdated software, security installs, or purchasing a CD with an installation code again – Office 365 is always up-to-date, equipped with built in security and available to purchase online.”

Unlike Windows XP use, which can be estimated by tracking how many websites are still accessed with the OS, there’s no concrete numbers on just how many Office 2003 clients are still being used worldwide.
