What is a Windows 8 'Child Session'?

Question

I'm currently writing a broker service which launches a process into arbitrary sessions based on certain criteria. Upon looking up the documentation for one of the APIs I use, I noticed that some new APIs have been added for Windows 8, controlling some new 'child session' feature (WTSIsChildSessionsEnabled, WTSEnableChildSessions, WTSGetChildSessionId).

The problem is that this new 'child session' feature is not documented anywhere as far as I can tell. I'd like to be able to 'future proof' my app and support this new technology if it's relevant to my application, but I can't figure out if it's relevant if I don't know what it is!

Does anyone know what exactly this is, or has a link to somewhere with some more information? (I ran searches on MSDN and Technet and came up empty-handed...)

Thanks.

Answer 1

All three of the MSDN pages to which you link contain the following remark. The linked page describes the Child Sessions feature.

For more information about child sessions, see Child Sessions.

I would guess that this features was added to support "simulator" debugging of Windows 8 Apps.
