Win8 RTM 正式版编译完成！版本号9200
7月8日的时候，软媒发表了那篇《Win8正式版：8600、8800还是8888？》，实际上，直到7月24日的时候，微软还是决定Win8 RTM 是Build 8888，甚至编译完成了 8888.16384.WIN8_RTM.120724-1555。但是到了7月25日，情况发生了变化，因为Win8的这个8888版本和微软内部的工具组发生了冲突，因此这个版本被废弃，从而选择了9200这个版本号。

吉利的版本号瞬间成了过往云烟，那么微软为什么会选择9200这个版本号呢？

微软内部选定版本号的规则相当复杂，总之一旦当初选定的版本号不适合，那么必须再选定末尾是00的版本号。
不管如何，这次算是尘埃落定了，而且Win8 Build 9200.16384.WIN8_RTM.120725-1247 这个版本已经在美国时间7月26日正式完成编译。

其他网站的消息依然是8888为正式版，但是软媒很确定，Win8 Build 9200.16384.WIN8_RTM.120725-1247 这个将是陪伴我们度过1年多时光的Windows 8系统的正式版版本号。

因为此次Win8 RTM版本号从8888变化到9200，导致Win9的第一个版本号也发生了变化，这个随后会有细节报导。

Windows 8 build 8888 and 9200 are both RTM candidates and the final selection by Microsoft would be done between two of them. Interestingly, 9200 is still the Windows 8 build not the post-RTM build for Windows 9. Build 9200 was compiled on 25 July, 2012 while 8888 was compiled a day before that but, both of them are from RTM branch of Windows 8

Canouna the well-known source of Windows 8 leaks, on WinUnleaked has updated the build list of Windows 8 which have both build 8888 and 9200 as the RTM candidates. According to Canouna, the final build would be selected in next 12 – 24 hours.
We previously, reported about Windows 8 build 8888 as the final RTM build but, now another build has been entered as the candidate for Window 8 RTM. The final selection would be done by Microsoft in a days’ time.

The Windows 8 RTM build number 9200 seems to be in line with RTM build Numbers of previous versions of Windows from Vista onwards. All are divisible by 100 and 16.
1.16*375=6000 Windows Vista RTM Build
2.16*475=7600 Windows 7 RTM Build
3.16*575=9200. Windows 8 RTM Build

You can notice a simple mathematical trend here
