Search the Internet for "spare parts for a model T ford" and you won't find Ford Motor Company at the top of any listings.
Search again for parts for a Ford Capri and you're likely to have the same problem. Why? Because times move on and companies have to devote their time and attention to new opportunities and stop spending time and resources on old products.
The same process applies in the computer industry. Back in 2001 Microsoft launched Windows XP and it bought a fresh change to how things were looking back then. A couple of years later, Microsoft launched Office 2003 and now both XP and Office 2003 are going to be shelved when it comes to "updates".
Support for older programs requires a team of developers to upgrade the software, ensuring that it contains the latest bug fixes and security patches. However, when you consider that this software is over 10 years old, you can understand why Microsoft and other software developers want to turn their attention and teams to keeping the up to date software protected and supported.
What does this mean for you? If you have XP or Office 2003 you need to be aware that your software will no longer receive updates around April 2014. You can still use the software, but as new security breaches are discovered, you won't get new protection from Microsoft.
"Why Move on ? I like XP!"
Good for you. If you're happy to take the time protecting your system and it runs well for you, great. We're not demanding that you change, but certainly would recommend that you consider upgrading as you'll have all the benefits of the new software along with the countless security and bug fixes over the years.
As anybody that owns a classic car will tell you, there's a certain pride and joy in running an older vehicle, but you have to be prepared to put the time and effort into keeping it running.
And as anybody that buys a brand new car will tell you, there's a certain amount of excitement discovering what all the buttons do.
