Hi everyone, I am a user of Windows 7. In order to increase the network speed of my computer, I firstly go to the control panel and then click "Turn Windows features on or off" to remove the tick mark from the Remote Differential Compression, but it doesn't show anything inside  the window that comes up. I tried it repeatedly but in vain.

Please suggest me the way out of it.

Answer:

You may experience poor file copy performance over the network in Windows 7 PCs. This could be caused by the Windows “Remote Differential Compression” engine. Remote Differential Compression is a Windows feature introduced in Windows Server 2003 and is available on all later versions of Windows. This Windows feature is enabled by default in Windows 7.

 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. RDC is different from patching-oriented different mechanisms, such as Binary Delta Compression (BDC), that are designed to operate only on known versions of a single file. BDC requires the server to have copies of all versions of the file, and differences between each pair of versions are precomputed so that they can be distributed efficiently from a server to multiple clients. There seems to be a problem with this Windows 7 and disabling this feature resolves the problem with slow file copy performance. 

To disable Remote Differential Compression, 

1. Click Start – Control Panel – Programs – Turn Windows features on or off 

2. Uncheck “Remote Differential Compression” and click OK.

3. Restart the computer and you should see an improved performance with copying files.
