Windows does have a home dir, but that's not where you want to place application settings

Application settings should go in a subdir of the directory specified by registry value
HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\Local Settings
The subdir should be of the form <company name>\<application name>.

Application data should go in a subdir of the directory specified by registry value
HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\Local AppData
The subdir should be of the form <company name>\<application name>.

Replace %USERPROFILE% with the value of $ENV{USERPROFILE}.
