// SetCurrentUserID is used to implement support for multi-user systems (only
// Windows 2022-11-25). On such systems, the uid is used to determine which
// user's state should be used. The current user is maintained by active
// connections open to the backend.
//
// When the backend initially starts it will typically start with no user. Then,
// the first connection to the backend from the GUI frontend will set the
// current user. Once set, the current user cannot be changed until all previous
// connections are closed. The user is also used to determine which
// LoginProfiles are accessible.
//
// In unattended mode, the backend will start with the user which enabled
// unattended mode. The user must disable unattended mode before the user can be
// changed.
//
// On non-multi-user systems, the uid should be set to empty string.
