Windows 8.1預(yù)覽版本月底就會(huì)公開(kāi)發(fā)布，但是其具體版本微軟卻并未透露。根據(jù)目前已知的消息，Windows 8.1的開(kāi)發(fā)經(jīng)歷了Milestone 1和Milestone 2兩個(gè)主要階段，并且在Windows 8.1正式版發(fā)布前，微軟僅會(huì)發(fā)布一個(gè)Beta版，也就是6月BUILD大會(huì)上即將到來(lái)的公開(kāi)預(yù)覽版(Preview)。

有消息稱，Windows 8.1將在8初完成RTM正式版，也就是公開(kāi)預(yù)覽版發(fā)布的一個(gè)月后。日前外媒拿到了一份列表，是微軟目前已經(jīng)提供給合作伙伴的Windows 8.1預(yù)覽版本，從中我們可以窺探到微軟的開(kāi)發(fā)進(jìn)度：
