Windows WSL Ubuntu sees wrong permissions on files in mounted disk
I noticed the owner of the file on Windows was "Administrators".
I changed that to be my user following this link and WSL started giving the appropriate permissions.
To summarize the steps here:
Left click -> "Properties" Option -> "Security" Tab -> "Advanced" Button -> "Change" button next to "Owner" -> In the input field write your user name and press "Check Names" button
Then press Ok until you close all the windows
I'm still not sure why I could access them in Windows but not on WSL.
