After five years and many twists and turns, Microsoft on Wednesday said development of Windows Vista is complete.
Windows chief Jim Allchin said Microsoft has signed off on the code: "It's rock solid and we're ready to ship. This is a good day."
Allchin said Vista will go on sale to consumers on 30 January. He said Microsoft is releasing Vista in five languages. The French, Japanese and Spanish versions were actually signed off on before the English version, according to Allchin.
