A number of third-party blogs are telling people they can speed up Windows Update downloads, and file copy operations, by turning off the Remote Differential Compression (RDC) feature on Windows Vista. This is 100% false. Neither Windows Update or file copy operations use RDC at all.

The RDC feature is simply a DLL that does not consume any system resources, except when you run an application that uses RDC specifically. If you disable RDC, any application that uses it will either not be able to take advantage of RDC or will simply fail. For more information on RDC see this link .
