• It is supported on all Windows operating systems that allow remote desktop connections.
• If both ONE_TS_OK and TS_OK are defined in a feature definition line, the ONE_TS_OK behaviour takes precedence.
• This keyword does not limit users accessing the system using the Fast User Switching feature in Windows

For example, if the feature definition line contains the ONE_TS_OK keyword and more than one user tries to run the application through a remote connection, the first user to check out f1 is successful but subsequent requests for the feature return an error. However, another user can access the system through a remote connection and check out a different feature.
