Can't upgrade from 14986 to 16179.

Hi,

My computer is Surface Pro and the Windows Insider Preview version is Bulid 14986.rs_prerelease.161202-1928. I was informed the new Insider Preview version 16179.1000(rs.prerelease). Having finished downloading and the install preparing, the system noticed me to restart it to install the new version. I followed the notice and restarted system. It went into the installing interface. But when the installing  percentage was 32%, the interface turned to the other interface which said my computer has  problems that has to restart the system suddenly. It has a ":-(" and a QR code. When the percentage turned 100%. A rollback interface told me that the system was rollbacking to the old Windows version, which was 14986. After that, although I had tried several times to upgrade the system, it failed everytime. Very disappointed.

Most importantly, everytime I started the system, I would receive a window said my 14986 will past due on May 1st and it will restart automatically in several hours. It has 8 days left from today and must affect my study and work.

So, I came to the Microsoft Community to turn to professiors to solve this problem.

Thank for your reply and suggestions.

你好，

我的電腦是Surface Pro，Windows內部版本為14986。昨日我接到新版本16179.1000的更新通知，我當即開始下載更新並且順利進入準備安裝階段，直到係統提示我重新啟動以開始安裝更新，一切順利到進入安裝界麵，但這時問題就出現了：當百分比艱難地上升到32%時，安裝界麵突然變成一個綠色為底色的，上麵有“:-(”和二維碼的類似藍屏的界麵(實際是綠屏)，上麵告訴我我的電腦出現故障需要重新啟動，Windows需要收集信息後立即重新啟動。當百分比100%後，進而進入的是係統回退界麵，告訴我係統正在回退到以前版本，即14986。重啟之後即使我嚐試再更新幾次，也無濟於事，每次都是失敗，這令我很煩惱。

更重要的是，每次我啟動電腦進入係統，都會有一個窗口告訴我我的舊版本即將在5月1日過期，過期之後係統會在幾個小時內自動重啟，距今隻剩下8天，這無疑對我的學習和工作帶來麻煩。

因此我來到微軟社區尋求各位專家的幫助。無論您回複的辦法是否能幫我解決這個問題，我都不勝感激。

謝謝！
