Fixing slow network file copy issues in Windows® 7
Let's find out the possible causes for slow network file copy issues in Windows 7.
Windows 7 provides access to support from Microsoft along with updates and download which may help you to get the most from your computer. The main benefits of Windows 7 system are its speed and responsive performance. Also, it provides a streaming media in your home. Windows 7 comes with exciting new and useful features. Despite of all these features sometimes Windows 7 system often experiences slowness in coping network files. This may be caused by the Windows 'Remote Differential Compression' engine. This Windows feature may get enabled by default in Windows 7. Remote Differential Compression (RDC) allows data to be synchronized with a remote source using compression techniques and it minimizes the amount of data sent across the network and hence slows down the coping of network files. Also if your network card drivers are not updated then you may face poor performance in copying network files.
The following are some tips to fix the issues:
- Disable Remote Differential Compression
- Disable the automatic adjustment for the TCP window size
- Use a new network card driver
Disable Remote Differential Compression
In order to disable the Remote Differential Compression, you need to click 'Start' and go to 'Control Panel'. Then select 'Programs' and there you need to turn Windows features on or off. Also you need to uncheck 'Remote Differential Compression' and click 'OK'. After that you need to restart the computer and you may see an improved performance with copying files.
Disable the automatic adjustment for the TCP window size
On the network you need to disable the automatic adjustment for the TCP window size in order check the reason for poor performance of coping network files. For that you need to click 'Start' button, and select 'Accessories' in 'All programs'. You need to select 'Command Prompt' and right click, and then select 'Run as Administrator'. At the command prompt, you need to type 'netsh interface tcp set global autotuninglevel=disabled'. After that exit the Command Prompt window and restart the computer.
By performing above steps, the issues may not get solved, so in such cases you need to use a new network card driver. For that you need to approach drivers manufacturers' websites and your computer website. Sometimes the presence of antivirus software scanning can block proper installation of drivers that are necessary for device function. So you need to turn off any antivirus or antimalware/spyware software temporarily while you install or update device drivers, and then turn it back on.
