Win 10 System Restore Fail 0x80070091
Question:
Below about says it all. I tried SysRes from two points, both with same failure.
System Restore did not complete successfully. Your computer's system files and
settings were not changed.
Details:
System Restore failed while restoring the directory from the restore point.
Source: AppxStaging
Destination: %ProgramFiles%\WindowsApps
An unspecified error occurred during System Restore. (0x80070091)
The two attempts were from: choose a different restore point>show more restore points type Backup. I really need this function to work. Any solutions out there?
Answer:
Renaming folder WindowsApps, reboot the system and try a system restore should cure the issue.
1.下载一个win10的iso镜像文件(官方原版的)
2.用ultraiso将镜像写入U盘(方法自己百度)
3.利用BIOS提供的启动顺序切换,从U盘启动,耐心等待
4.选择完语言下一步,第二个画面左下角,点“修复计算机(R)",点“疑难解答”,点“命令行提示符”
依次敲入命令:
c:
cd "Program Files"
md "WindowsApps-"
xcopy "WindowsApps" "WindowsApps-" /s /e /y /h
rd "WindowsApps"
关闭命令行窗口,点“疑难解答”,点“系统还原”,再执行就OK了。

Addendum: It seems that the issue has been fixed in Windows 10 Creators Update. And there is a batch file to fix the issue. Further details may be found here:
