windows 10 passwords are for login and not drive access, unless its encrypted using MSFT's bitlocker
or to use variations of Truecrypt and its descendants.
when you mount a windows drive as a USB then you only have to worry about ownership and permissions
at the root level, and if windows needs more help, computer management/storage and right click the drive
gets you to the place where you can change ownership and permissions and propagate through the folder
hierarchy. less than one minute.
if its the app that needs a password AND/OR the windows login password is corrupted/changed, you can
change the password at the login screen. and once in , you can delete the app, or re-install the app.
next thing, is that it is rather difficult for an app to change windows security credentials, of the many but in this
case the Windows logon/login password. after years of kernel work, I would not be surprised if it is done this
way but it would attribute magical powers to some app developer.
Occam razor's says the password was changed using standard interfaces. you can download a simple
app to change this back or retrieve it, and unnecessary to use another set of tools.
if this is the only way, then you'd need to know a lot more about the drive, there are issues with Fat32
with large drives, NTFS support by many apps, and some requirement for ext3/4/next file systems.
