MORE INFORMATION

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

To comply with current Internet standards (Request for Comments 2068), Internet Explorer limits the number of simultaneous downloads to two downloads, plus one queued download. This configuration is a function of the browser. However, as connection speeds increase, and the number of total connections that are allowed to Internet servers increase, the two-connection limit may be restrictive. To increase the number of simultaneous connections that are allowed to 10, follow these steps:
1.Start Registry Editor (Regedt32.exe).
2.Locate the following key in the registry:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings
3.On the Edit menu, point to New click DWORD Value, and then add the following registry values:
Value name: MaxConnectionsPer1_0Server
Value data: 10
Base: Decimal

Value Name: MaxConnectionsPerServer
Value data: 10
Base: Decimal
4.Quit Registry Editor.
This procedure is for informational purposes only. Changing the maximum number of connections beyond two is a violation of Internet standards; Microsoft does not recommend this procedure for use outside closed networks.
