This article assumes that reader has basic knowledge of Windows Registry and understands its criticality. I have tested it on Windows 9X and NT not sure about Windows 2000 and XP. If somebody tests success please let me also know.


As I mentioned in last article, Windows stores most of its settings in its registry. That is for quick referance, faster access, and unique way to access the settings. Basically, this article is just the information about some settings related to Internet Explorer. I suggest that you do not modiy registry, unless and until you read and comply with all the terms and conditions of Microsoft Copyrights.

Microsoft has provided users with Internet Explorer Administration Kit 6 for customization. In any case, Author can never be held responsible for the damages to Registry or User System. The unsolicited changes might damage the system.

Internet Explorer reads many of its basic properties from the Windows Registry. The location is HKEY_USERSDefaultSoftwareMicrosoftWindowsInternet ExplorerMain . It has several keys that have specific values and meanings. For example, the ‘Start Page’ Key will specify the URL of your home page(i.e. when you press the HOME button in borwser).

This is about the Windows Registry and Internet Explorer. I found this when I was working on some application development where I wanted to use the Internet Explorer as per my needs on a user’s machine. The major focus of this article is to find easy ways for application. Next time, I will cover some more on the Windows Registry.
