【win10】可能解决开始菜单无法打开的问题

I got exactly the same problem and here‘s how I fixed it. Everything was done from desktop.
1- Create a folder on desktop: mount
2- Copy install.wim to desktop. (used the ISO downloaded from techbench)

Open Admin Command prompt, copy/paste each line and run:

1. Dism /mount-wim /wimFile:%USERPROFILE%\Desktop\install.wim /index:1 /MountDir:%USERPROFILE%\Desktop\mount
2. Dism /Online /Cleanup-Image /CheckHealth
3. Dism /Online /Cleanup-Image /RestoreHealth /Source:%USERPROFILE%\Desktop\mount\windows /LimitAccess
4. Dism /unmount-wim /Mountdir:%USERPROFILE%\Desktop\mount /discard
5. re-run: sfc /scannow
