To clone the card to a .img file on your windows laptop, you could use the linux dd command from WSL. On linux, the command would be of the form:
dd if=/dev/mmcblkX of=/path/filename.img bs=1M
Where if is the source device. I’m not sure what this name would be under WSL.
Apparently, you can also use the windows utility win32diskimager, although I havnt tried it. Balena Etcher can apparently clone a card to another card but cannot save a .img file.
Otherwise try a google search - there are a number of tools out there to write an .img file to an sd card, some could undoubtably read the card and save it as a file as well.
