24 bit RDP under Windows XP
By ThinGuy on Feb 21, 2006
Did you ever notice that when you connect to Windows XP via RDP, some colors and icons are just a bit off? This is because the single user XP RDP Server defaults to 16 bit color depth even though it is capable of running 24 bit. While there is no mmc snap in for increasing it, it can be done via the registry.
Open up the Registry Editor (Start -> Run -> regedit) and navigate to the following key:
Change color depth to 4.
Reboot Windows XP to have the change take effect.
