  * the windows versions stores its settings in the registry under key ''HKEY_CURRENT_USER\Software\AndreasSchmidt\WinFIG''
  * the Linux versions stores its settings in the user's home directory under ''~/.config/WinFIG/WinFIG.conf'' 

It is safe to remove the settings. WinFIG will restore them to the defaults on the next startup.
