WinSCP uses HKCU registry.

In general, you will find everything you need at https://winscp.net/eng/docs/config, particularly in this section: https://winscp.net/eng/docs/config#auto

i understand your question
the challange is i am locking for a solution when you have multiply users on a windows rds enviroment and every users can save his settings on the system wihtout conflicting with other users..

the solution can be a HKCU user registry setting
or a ini file for every users.

Why do you want to use the INI file instead of the default registry?
