How can I delete files from a install.wim?

[myvanherbert]

Hi,

I just made the mistake of capturing an old Windows 10 install disk image without first removing documents (files) in Documents, Downloads and Pictures folders. If possible, how can I now delete those files from the install.wim? I understand that I would first have to mount the install.wim. But I don't know what to do next.

Thank you in advance.

If you are familiar with command prompts, this is not difficult for you.
