Do not extract Win8.1 install.wim file

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", execute the following command

dism /get-wiminfo /wimfile:"F:win8.1sourcesinstall.wim"

Version 1 is Win8 Pro version as shown 2 is Windows8 Standard Edition, I am Win8 Pro naturally selected 1

Second, unzip the image:

I have 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

After the command is completed, open c:111 as shown in the figure. After the decompression is completed, you can choose to copy the required files.

Third, uninstall the image:

After the file is extracted, you no longer need to uninstall it. Before uninstalling, close the image folder and execute the command:

dism /unmount-wim /MountDir:c:111 /discard

When the command is completed, c:111 will become an empty folder.
