To turn off Remote Differential Compression,

  • Click START and type features.
  • Second on the list that appears is Turn Windows features on or off. This brings up the following window.

  • Untick it and press OK.
  • Select yes to restart your system.

You should now see a substantial improvement in transfer speed.
