On the 25th of October, 2001, Windows XP was available on the shelves for sale. XP dominated the OS usage from 2003 to 2011 until recently 7 overtook it, Microsoft encourages people to move on from Internet Explorer 6 to the latest explorer 9, In an effort to upgrade from the good ol' XP
Microsoft's own Internet Explorer 9 only runs on Windows 7 or Vista because of graphics acceleration support. Also the latest windows live setup which includes movie maker and good stuff doesn't support XP. Microsoft will stop all support for Windows XP on the 8th of April, 2014, also those of you who haven't upgraded to the service pack 3 it's high time you do it because official support is only available for the SP3. A decade is too long and if you are still on the rusty old XP , seriously it's time to upgrade, a solid reason for this is that XP still continues to be the breeding ground for malware, so beware your data and your valuable personal information may be at stake. Better be safe than sorry.
