Remote Desktop Connection Registry Settings (Compact 7)

3/12/2014

You can configure Remote Desktop Connection by using the Remote Desktop Connection registry settings.

If the OS uses the Windows Thin Client Shell, you can configure user preferences for Remote Desktop Connection by using the following entries, located in the key HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client\Default.

Many of the settings in the device registry also correspond to options in the device's Remote Desktop client user interface (UI).

If the OS uses the Windows Embedded Compact Standard Shell, you must instead configure these user preferences by using the corresponding keywords located in the .rdp file. See Remote Desktop Connection .rdp File Keywords for more information.

DisableRDP7BitmapCompression

REG_DWORD

Disables the support for Remote Desktop Protocol 7.0 bitmap compression on RDP Client.

When establishing a RemoteFX session, the server may send non-RemoteFX data to the client in addition to RemoteFX data. Non-RemoteFX data may use an RDP 7.0 bitmap codec for compression, which requires support for the Streaming SIMD Extensions 2 (SSE2) instruction set in the processor. If a platform does not support the SSE2 instruction set, the RDP 7.0 bitmap codec will not be used.

Set to 0 (zero) to enable the codec. Set to 1 to disable the codec.

The FullScreenRFXOnly setting is not used in software decoding in RemoteFX. If this setting is used with software decoding, the contents of the device display screen might not update. When FullScreenRFXOnly is enabled, the RDP client does not call the ESCAPE_COPY_2BMP escape function. When this key is enabled, the RDP client will not present any RemoteFX data on screen and it becomes the responsibility of the display driver to handle the display of decoded RemoteFX data. When this key is enabled the blue connection bar will be hidden in RemoteFX sessions.

Set to 0 (zero) to disable support. Set to 1 to enable support.
