【业内资讯】微软停止预装Win7：Win9上位

Some people try updating to Windows 8.1 from the Windows Store, after some boot times they get this error message: Couldn't update to Windows 8.1. We restored your previous version of windows. Error code: 0x80070002 - 0x20009 . And then the system automatically restores to Windows 8.If you experience this error code I suggest that you should try one of the below methods.Method 1:If you connected a second drive or any external drive to your PC (a SSD or HDD) the upgrade will fail if the second (original) drive is not disconnected. Just remove the secondary drive and all external drive, reboot and try installing the Windows 8.1 update.Method 2:If you do not have any external drive connected to your PC, boot the computer in a clean boot state and then try to install and check. Booting the computer in a clean boot state uses a minimal set of drivers and start-up programs. A clean boot helps eliminate software conflicts.You can refer to this article for more information:http://support.microsoft.com/kb/929135Good luck and feel free to leave your comment on this post if you try any method above.你照着步骤试试看。国外论坛发的。
