Uninstall the Win8/Win8.1 install.wim file without software

First, check the image version:
The image contains multiple versions, you need to confirm the version you need, my image path is "F:win8.1sourcesinstall.wim", then execute the following command
dism /get- Wiminfo /wimfile:"F:win8.1sourcesinstall.wim"
As shown in the figure, version 1 is Win8 Pro version 2 is Windows8 standard version, I am Win8 Pro natural selection 1

2, decompression mirror :
I want to extract the install.wim file into the c:111 folder, execute the command for this:
dism /mount-wim /wimfile:"F:win8.1sourcesinstall.wim" /index:1 /mountdir:c:111
Open c:111 after the command is completed. If the decompression is completed, you can choose to copy the required files.

Third, uninstall the image:
After the extraction of the file is no longer necessary to uninstall, close the mirror folder before uninstalling, and then execute the command:
dism /unmount-wim /MountDir:c:111 /discard
After the command is completed, c:111 will become an empty folder.
