There is a small .exe in the bb folder you can run:
bb\data\installers\fileassoc.exe

Alternatively you can do it from within Band-in-a-Box - there is an option under the file menu (this requires that you run Band-in-a-Box 'as an administrator' (right-click on the .exe / shortcut) because it needs to change a registry setting.

The "default app" setting in Windows 10 doesn't seem to work for some people, not sure why ... and it's not just with Band-in-a-Box, but other files like text files for example.
