The bug caused a crash that required a complete reinstall of the OS.
PC manufacturers that expected to get their hands on the final version of Windows Vista today will have to wait a couple more weeks for the operating system, according to sources familiar with Microsoft Corp.'s plans.
Microsoft originally targeted today for Vista's release to manufacturing, but a last-minute bug that "took most of the Vista team by surprise" caused an unexpected delay, said Ethan Allen, a quality assurance lead at a Seattle high-tech company that tests its products for Vista. Allen also oversees hotfix.net.
