Use the instructions in Win8 to extract the install.wim file

In the Win8 system, the install.wim file, the Rar decompression tool alone is unsuccessful, and the file is damaged. Even if I change the 7Z, I can't do anything about it. After my test, the file is good and not damaged, but the software does not support it. However, under the Windows
8 system, I still have a way to decompress.

Operation Steps

Type Win+R and type cmd to open a command prompt. Enter the command: dism /get-wiminfo /wimfile:"F:\\win8.1\\sources\\install.wim" because my file is stored under F:\\win8.1\\sources\\install.wim.

Below I have to extract the install.wim file into the c:\\111 folder. To do this, execute the command: dism /mount-wim /wimfile:"F:\\win8.1\\sources \\install.wim" /index:1 /mountdir:c:\\111

Open the folder and see that the extraction is successful.

After extracting the file, you no longer need to uninstall it. Close the image folder before uninstalling, and then execute the command: dism /unmount-wim /MountDir:c:\\111 /discard
