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

        Today, I used the pressure to decompress the Windows 8.1 install.wim file, and actually prompted the file to be corrupted. I still changed the 7Z; in fact, the file is good. However, these softwares are temporarily not supported, but can be done manually using the dism command.
First, check the image version:
The image contains multiple versions, you need to confirm the version you need, my image path is "F:\\Win8.1\\sources\\install.wim", then execute the following command
dism /get-wiminfo /wimfile:"F:\\Win8.1\\sources\\install.wim"
As shown in the figure, version 1 is Win8 Pro version 2 is Windows8 standard version, I am Win8 Pro natural selection 1

Two, unzip the image:
I want to extract the install.wim file into the c:\\111 folder, execute the command for this:
dism /mount-wim /wimfile:"F :\\Win8.1\\sources\\install.wim" /index:1 /mountdir:c:\\111
Open c:\\111 after the command is completed. If the extraction is complete, 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.
