Internet Explorer is available for free at Windows.Microsoft.com, as of 2015. While other websites offer the download, the Microsoft site is the developer's official source. The bottom of the Web page includes links to get IE in older versions or different languages. Information on the Web browser's latest features and technical support are also available.
The official download sets the default search engine to Bing and the default homepage to MSN. These selections can be cancelled by unchecking the box beneath the download button or changed after the download is completed. Downloading IE implies acceptance of Microsoft's terms and conditions.
IE's system requirements include a computer with a 1 gigahertz, 32-bit or 64-bit processor; an operating system of Windows Vista 32-bit or higher; 512 megabytes of available memory; an Internet connection and a compatible clicking device. The system also requires hard drive space, with the amount varying based on the operating system; it ranges from 70 MB for older 32-bit setups to 200 MB for Windows Server 2008 64-bit setups. Internet Explorer does not function if these specifications are not met.
Many of the other sites that offer the download, such as Cnet.com, force users to navigate away from that site and onto another. Downloads from untrusted sources may be a security risk.
