Ok, it has been a while since I've had Kodi installed on Windows. The file is in one of two places %APPDATA%\Kodi\temp\kodi.log (C:\Users\Your User Name\AppData\Roaming\Kodi\temp\kodi.log) or %APPDATA%\Kodi\kodi.log C:\Users\Your User Name\AppData\Roaming\Kodi\kodi.log

Just recreate the problem with logging on, then Alt-Tab out of Kodi and pull the log. You can then paste it to one of the two sites above I listed.

Hope that helps. Happy bug reporting.

Very helpful, thank you sir.
