If you need to troubleshoot how a WIM image was created, you can try examining its setupact.log file by performing the following steps:
1. Use the Dism /mount-wim command to mount the WIM file to an empty folder such as C:\mount
2. Use the command cd C:\mount\Windows\panther to open the Panther folder on the mounted Windows installation
3. Open the setupact.log file in the Panther folder using Notepad.
