Problem description

By default, Windows Internet Explorer 7 and earlier versions limit the number of files that you can download at one time to two. Windows Internet Explorer 8 and Windows Internet Explorer 9 limit the number of files that you can download at one time to six. This change reflects the faster connection speeds that are now typical for most users. For dial-up connections, the limits from earlier versions still apply. 

This article helps you increase the number of files that you can download at one time to 10.


To have us fix this problem for you, go to the "Fix it for me" section. If you would rather fix this problem yourself, go to the "Let me fix it myself" section.

More information

To comply with current Internet standards (Request for Comments 2068), Internet Explorer limits the number of concurrent downloads to two , 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 available to Internet servers increases, the two-connection limit may be restrictive.
