"5 years ago today Windows XP was launched worldwide after it had RTM’d a month earlier.
It has been without a doubt the longest running operating system Microsoft has ever produced. Microsoft typically updated the client version of Windows every 2 years with Windows 95 being released in early 1996, the successive OSR updates until 1997 when Microsoft were hammered by anti-trust cases for bundling Internet Explorer 4.0 with Windows 95 OSR2, Windows ’98 in 1998, Windows 98 Second Edition in 1999 and Windows Millennium in the February of 2000 after an extremely short beta cycle."

I can’t believe I forgot this one. Funny how time flies, Windows XP is said to be on over 400 million desktops world wide I am sure this is based on registered/activated installations, which does not account for the many pirated installs in use pushing it to 600 million. There is nothing spectacular to account for here except that regardless of all that XP has been through, (vulnerabilities, activation, Linux/Open Source), it continues to stand the test of time and will be running on many systems for a very long time post Vista. A culmination of ease of use from Windows 98 in areas such as hardware detection, application compatibility and gaming plus the strength of the Windows 2000 kernel, Windows XP deserves to be called a highly respectable desktop operating system. Happy B-day XP!
Another famous MS OS, Windows 95, celebrated its 11th birthday in August of 2006.
