Symptoms
When connecting remotely with Remote Desktop Connection, the environment variables CLIENTNAME and SESSIONNAME are added to each process that is started.
If you set the Folder Option "Launch folder windows in a separate process" and later launch an application from an additional Explorer window, the application will not see these additional environment variables.
If you set the Folder Option "Launch folder windows in a separate process" and later launch an application from an additional Explorer window, the application will not see these additional environment variables.
Cause
The additional Explorer window is not a child window of the parent Explorer.exe process, but launched from the system process. Therefore it does not inherit the environment from the Explorer main window.
Resolution
If your application relies on these variables, remove the folder option "Launch folder windows in a separate process".
