"Rock solid" Vista ready to roll, says Microsoft

NEWS

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.

The software maker has scheduled a 30 November press conference to announce the new operating system, along with Office 2007. The releases, which mark major updates to Microsoft's two key money-makers, are scheduled to be made available to consumers early next year. Vista is slated to arrive on new PCs and on store shelves in January.

Make your voice heard - take our latest poll. Microsoft's move caps an intense period for the Windows development team, which has raced to stamp out a number of bugs in test releases before declaring Vista code "golden" or final.

The company issued the first near-final release candidate of Vista in September. A second release candidate was made available in October.

The release of Vista will mark the first fully fledged update to the desktop operating system since Windows XP in 2001. Among the changes coming with Vista are a new graphics engine and user interface, improved desktop searching and a new media player and web browser. Also included are "under the hood" improvements in areas such as security and manageability, as well as power management.

Vista's debut has been a long time in the making. Microsoft announced detailed plans for a new Windows release, code-named Longhorn, at an October 2003 developer conference.

Eventually though, that ambitious plan was deemed unworkable, with the Windows team sent back to the drawing board to find more manageable ways to achieve some of the same goals, such as improved searching. Microsoft announced the change in plans in April 2004, saying its shift would allow it to have Vista on store shelves by this year's holiday season.

In March, though, Microsoft said that it would not have Vista ready for new PCs by the holidays. Instead, it would make it available to businesses in November and delay the broad launch until January.

With the code now final, computer makers can start their final testing and start building PCs with the new OS, though they are not expected to hit store shelves until Microsoft's formal launch in January.

Microsoft also needs hardware and software makers to finish writing drivers so that things such as mouses, keyboards, cameras and printers all work smoothly with the new OS.

While Wednesday's announcement is the culmination of a long process, it is likely to be many months if not years before most businesses are running Vista.

Microsoft has ambitious goals for Vista's deployment in businesses. Still, the company predicts that only 20 per cent of PCs in large enterprises will be running Vista a year after launch. Only about 10 per cent of businesses ran Windows XP, Vista's predecessor, a year after its release, according to research company IDC.

Allchin said: "I've talked to some customers that are going to move quickly." Others, he said, will upgrade as they buy new machines. "Businesses need to do their testing. They need to be very comfortable," he added.

As for consumers, he said the move to Vista will be "fast and immediate".
