Half Of Businesses Still Use Windows 2000
bonch writes "An AssetMetrix study shows that half of business are still running Windows 2000 four years after the release of Windows XP, and that usage of Windows 2000 has only decreased by 4% since 2003. Microsoft will officially stop supporting Windows 2000 by the end of this month, offering one last update rollup later this year. Windows XP's slower adoption illustrates Microsoft's difficulty in competing with the popularity of its own software platform, and makes it more difficult for Microsoft to convince people to upgrade when Longhorn is released late next year."
I have not run into a compelling reason to upgrade from Win2k to XP. Win2k has been very stable for me. It seems that my XP boxes get more security patches than my Win2k boxes. I don't need all the eye candy of XP.
It has to be released then according to MS: http://www.microsoft.com/windows/lifecycle/default .mspx
Check out the table. Notice how the licencing end dates run out at the end of this year for OEMs and next year for system builders? Longhorn has to fill that spot or the contracts need to be renegotiated.
