Server 2012 RDS question regarding session collections

Hi there,

I can't seem to find an answer to this....

My understanding is that in server 2012 you can only have a session collection in RDS do 1 role at a time, that being RemoteApps or Remote Desktop.

I've currently got a single 2012 R2 Server setup for RDS with a session collection but have had to make an unsupported registry change to publish the remote desktop to web access.

I guess my question really is, why does server 2012 restrict you to one or the other instead of allowing you to host both RemoteApps and Remote Desktop session from the same session collection / server?

Ideally we'd like to host both remote apps and remote desktop sessions from the same server, like we similarly do with Citrix.

Thanks,

Will
