Being that I write about a wide variety of technologies, I find myself constantly downloading files from TechNet and other sources. It isn’t often that I have to do bulk downloads, but when I do, I have always found it frustrating that Internet Explorer limits the number of simultanious downloads that you can perform.
In the past the solution to this problem was to modify the registry. By performing the following registry modifications, you can configure IE to allow up to ten simultaneous downloads:
Navigate through the Registry Editor to HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings
Create a new DWORD named MaxConnectionsPerServer and assign it a value of 0000000a
Create a new DWORD named MaxConnectionsPer1_0Server and assign it a value of 0000000a
Keep in mind that editing the registry is dangerous, and that you can destroy Windows, Internet Explorer, or your other applications if you make a mistake. Therefore, you should create a full backup before you try that technique.
A better solution to the problem is to upgrade to Internet Explorer 8. Although I haven’t seen any official documentation, the simultaneous download limit seems to be gone. I decided to see how far I could push Internet Explorer this morning, and initiated 40 simultaneous downloads!
