The user-mode screen capture driver is the default option to capture the remote desktop for all supported platforms. It runs as 32-bit x86 user mode code, but can capture either x86 or x64 systems, and is the only supported screen capture technology for Remote Desktop Services sessions.
When user-mode screen capture is selected, the amount of bandwidth used to capture and transmit remote desktop screen can be restricted or "throttled" by reconfiguring a user-mode screen capture profile. The default profile is "High Quality/High Bandwidth" but other profiles corresponding to smaller bandwidth limits are available. See "Bandwidth throttling" for more information. The Screen tab indicates which user-mode screen capture profile is applicable.
