In a previous post I linked to a TechNet article that documented the custom settings for the RDP file. In a true case of “wait there’s more!” I have more to show that were not documented here, though will be soon. In the meantime though:

allow font smoothing:i:1

allow desktop composition:i:1

disable full window drag:i:0

disable menu anims:i:0

disable themes:i:0

disable cursor setting:i:0

I usually insert these 6 settings into my custom RDP settings as they are required to enable Aero Glass in both RDSH Servers (through the Gateway and Broker) and VDI implementations.
