The final build number is expected to be 6000.16386.061101-2205, I'm told. (Readers may recall that WinInfo broke the news that Microsoft would iterate Vista to build 6000 for the final release way back on August 25.)

In its quest to finalize Windows Vista, Microsoft has faced two hurdles in recent days, one technical and one a bit more unusual. The proposed final build was marred by a few late breaking bugs, which the company expects to squash over the weekend. Meanwhile, a power outage in the Windows build lab Friday night prevented Microsoft from creating a new Vista build that night.
