Paul Thurrott has recently reported that his sources at Microsoft have confirmed this weekend that Windows Vista is set to be finalized as early as Monday and released to manufacturing. The final build number is expected to be 6000.16386.061101-2205, apparently.
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.
