Disable Remote Differential Compression

Speed up file transfers across a network in Windows Vista by disabling Remote Differential Compression.

Introduction

Remote Differential Compression (RDC) allows data to be synchronized with a remote source using compression techniques to minimize the amount of data sent across the network.

Many pre-Windows Vista computers and devices are not compatible with RDC which makes transferring files across a network slower for a Windows Visa computer because it’s trying to use RDC.

This guide shows you how to speed up your Windows Vista network transfer by disabling Remote Differential Compression (RDC) in Windows Vista.

Disable Remote Differential Compression

  1. Open the Control Panel.
  2. Open Programs and features.
  3. Click Turn Windows features on or off.
  4. Uncheck Remote Differential Compression.

    Thanks. Any reason you would NOT want to do this?

  2. Brent Trahan says:

    If all devices on your network (router, computers, other network devices) support RDC it’ll help speed your network up a bit.

    In Vista Is there a way to set one user limited account to automatically be a super powerful account (in my case for video editing)- i.e force power setting to max, to suspend back up, suspend defrag, auto save, restore points, auto updates and any other CPU or Disk hungry “services” that kick in without warning, but retain all these facilities on the other accounts? If this could be done by some macro or script during logon I would have thought this would be usefull to many vista users.

    Thanks Dave

    Dave w in a business enviroment you use Group Policy this is used to set default settings for users

    from vista i type in the run bar mmc (this runs the microsoft management console) and select the group policy object you can then set the security on it so it only applies to certain users or computers

  5. David Walker says:

    RDC is just a DLL, and file copy using Vista is not “trying” to use RDC by default. Removing the DLL has no effect on file copy speed.

  6. Ned says:

    David is correct, this is bunk, and this artgicle should be corrected if MaximumPcGuides has any belief in accuracy:
