Internet Explorer, abbreviated IE or MSIE, is a proprietary graphical web browser made by Microsoft and included as part of the Microsoft Windows line of operating systems. It is the most widely used web browser today.

Microsoft has shipped Internet Explorer as the default browser in all versions of Microsoft Windows since Windows 95 OSR1. The last major upgrade to Internet Explorer, 6.0 SV1[1], is included in Windows XP Service Pack 2 and Windows Server 2003 Service Pack 1 only. Beta versions of Internet Explorer 7 for Windows XP SP2 have been available since July 27, 2005 and versions specific to Windows Server 2003 as well as for 64-bit editions of Windows will also be released, though it won't be available for older versions of Windows. Internet Explorer versions, prior to the one included in Windows XP SP2, are also available as a separate download for versions of Windows uptil Windows XP.

In the past, Internet Explorer was also developed for several other operating systems: Internet Explorer for Mac and Internet Explorer for UNIX (the latter for use through the X Window System on Solaris and HP-UX). All of these versions have ceased active development.

Internet Explorer is currently known as Microsoft Internet Explorer, but the name will change to Windows Internet Explorer with the release of Internet Explorer 7.

History

Internet Explorer 4.0 under Windows
Main article: History of Internet Explorer

Internet Explorer is derived from Spyglass Mosaic, an early commercial web browser. In 1995, Spyglass Mosaic was licensed by Microsoft in an arrangement under which Spyglass would receive a quarterly fee plus a percentage of Microsoft's revenues for the software. Although bearing a name similar to NCSA Mosaic, which was the first widely used browser, Spyglass Mosaic was relatively unknown in its day and did not use any of the NCSA Mosaic source code [2].

Internet Explorer 3 was the first major browser with CSS support released in August, 1996 and it could handle the PICS system for content metadata. The improvements were significant, compared to its main competitor at the time, Netscape Navigator.

The browser was not widely used until version 4, which was released in October 1997 and was integrated with the Windows 98 operating system. This integration, however, was subject to numerous criticisms (see United States v. Microsoft). Version 5, released in September 1998, was another significant release that supported bi-directional text, ruby characters, XML and XSL.

Version 6 was released on August 27, 2001, a few weeks before Windows XP. This version included DHTML enhancements, content restricted inline frames, and better support of CSS level 1, DOM level 1 and SMIL 2.0. The MSXML engine was also updated to version 3.0. Other new features included a new version of the IEAK, Media bar, Windows Messenger integration, fault collection, automatic image resizing, P3P, and a new look-and-feel that is in line with the style of Windows XP.

On February 15, 2005, Microsoft Chairman Bill Gates announced that the new version of its browser will be released at the RSA Conference 2005 in San Francisco [3]. The decision to update the browser occurred in the wake of a decline in the use of Internet Explorer for the first time. Microsoft also stated that Internet Explorer 7 will only be available for Windows XP SP2 and later, including Windows Server 2003 SP1 and Windows Vista. The first beta version of the browser was released on July 27, 2005 for technical testing, and a first public preview version of Internet Explorer 7 (Beta 2 preview: Pre-Beta 2 version) was released on January 31, 2006. Version 7 is intended to defend users from phishing as well as deceptive or malicious software, and also features full user control of ActiveX, and better security framework. It includes important bug fixes, enhancements to support the web standards, improvements in HTML 4.01/CSS 2, Tabbed Browsing, Tab preview and management, and web feeds reader.

Features

Main article: Features of Internet Explorer
The pop-up blocker included in Internet Explorer 6 SP 2

Internet Explorer has been designed to view the broadest range of web pages and to provide certain features within the operating system, including Windows Update. During the heydays of the historic browser wars, Internet Explorer superseded Netscape by supporting many of the progressive features of the time.

Component architecture

The Component Object Model (COM) technology is used extensively in Internet Explorer. It allows third parties to add functionalities via Browser Helper Objects (BHO); and allows websites to offer rich content via ActiveX. As these objects have the same privileges as the browser itself (in certain situations), this raised concern over security. This issue was addressed in Internet Explorer 6.0 Service Pack 2, which provides an Add-on Manager for controlling ActiveX controls and Browser Helper Objects. Internet Explorer 7 provides a "No Add-Ons" version (Under Programs/Accessories/System Tools) to address this issue, as well.

Usability and accessibility

Tabbed browsing in Internet Explorer 7 Beta 2 preview

Since it is tightly integrated with the operating system, Internet Explorer makes use of the accessibility framework provided in Windows. Internet Explorer is also a user interface for FTP, with operations similar to that of Windows Explorer.

The ability to block popup windows was introduced with Internet Explorer 6.0, Service Pack 2.

Tabbed browsing can be added to Internet Explorer 6 by installing Microsoft's MSN Search Toolbar, and is natively supported as of Internet Explorer 7.

Security framework

Internet Explorer uses a zone-based security framework, which means that sites are grouped based upon certain conditions. It allows the restriction of broad areas of functionality, and also allows specific functions to be restricted.

Patches and updates to the browser are released periodically and made available through Windows Update website. Although security patches continue to be released for a range of platforms, most recent feature additions and security improvements are released for Windows XP only. A report in April 2005 showed that only 24% of corporate PCs had upgraded to XP SP2.

Internet Explorer 6 Service Pack 2 provide Download Monitoring and Install Monitoring that user can choose to download, or not to download and, choose to install, or not to install Applications, Executables and Installations. This prevents installation of Spywares, Adwares, Viruses or Malwares.

Standards support

Internet Explorer almost fully supports HTML 4.01, CSS Level 1, XML 1.0 and DOM Level 1, with minor implementation gaps. It partially supports CSS Level 2 and DOM Level 2, with some implementation gaps and conformance issues. It supports XHTML 1.0 to the extent that HTML 4.01 compatibility guidelines are followed. Internet Explorer uses DOCTYPE sniffing to choose between "quirks mode" (renders similarly to older versions of MSIE) and standards mode (renders closer to W3C's specifications) for HTML and CSS rendering. It fully supports XSLT 1.0 or the December 1998 Working Draft of XSL, depending on the version of MSXML (a dynamic link library) available. It also provides its own dialect of ECMAScript called JScript.

Proprietary extensions

Internet Explorer has introduced an array of proprietary extensions to many of the standards, including HTML, CSS and the DOM. This has resulted in a number of web pages that can only be viewed properly using Internet Explorer. Many view this as an example of what is called "embrace, extend and extinguish" (EEE), a way to drive competitors out of business by forcing them to use proprietary technology that a company controls, resulting in vendor lock-in. Netscape Navigator up to version 4.7 was also responsible for massive proprietary extension of the core web standards, but was not criticized for it as much.

Version 7.0

Internet Explorer 7's "Quick Tabs"

Version 7.0 of Internet Explorer has been renamed to Windows Internet Explorer, as part of Microsoft's rationalization of component names that are included with Windows. Set to ship with Windows Vista, and as a separate download for Windows XP with Service Pack 2 and Windows Server 2003 Service Pack 1, large amounts of the underlying architecture, including the rendering engine and security framework, have been completely overhauled. Partly as a result of these security enhancements, the browser will be a stand-alone application, rather than integrated with the Windows shell, and it will no longer be capable of acting as a file browser.

The Windows Vista version will incorporate additional security measures, most significantly "Protected Mode", whereby the browser runs in a sandbox with even lower rights than a limited user account software. As such, it can write to only the Temporary Internet Files folder and can not install start-up programs or change any configuration of the operating system. This is expected to increase the security of the system considerably.[4]

On January 31st 2006, Microsoft released a public preview build (Beta 2 preview: Pre-Beta 2 version) of Internet Explorer 7 for Windows XP Service Pack 2 (not for Windows Server 2003 SP 1) on their web site. It stated that more public preview builds (possibly Beta 2 in April) of Internet Explorer 7 will be released in first half of 2006, and final version will be released in second half of 2006.[5]

New features

Internet Explorer 7's Web feed reader
  • Version 7 supports tabbed browsing, which has been a popular feature in competing web browsers for some time. In addition to this, there is a feature called "Quick Tabs", which displays a thumbnail preview of opened tabs, treating tabs like Exposé treats application windows. With this new feature, user can find, open, close, and refresh opened tabs easily.
  • A search box has been added to the top-right corner, to do fast searches using a search engine. MSN Search is the default[6], but additional providers may be added. Microsoft provides a list of common providers, but any web site can identify itself as having a search capability.[7]
  • Long-awaited support for per-pixel alpha channel transparency in PNG images has been added.[8]
  • Feed reader integration in Web feeds support is built in version 7.0. The feed reader is fully integrated with the browser, so that user can read web feeds (RSS or Atom) without an RSS reader. It also discovers web feeds automatically. Updates to web feeds can be retrieved when the web browser isn't running. The web feeds feature set is also available to third-party developers through API's, so that the list of subscribed feeds (as well as their current contents) can be used. [9]
  • ActiveX Opt-In blocks ActiveX Control unless it allowed to be installed. This feature improves security from unverificable and vulnerable controls. ActiveX controls can be chosen to be installed on Information Bar. User can turn on and off ActiveX Contol by using Add-on Manager.
  • A number of improvements to CSS support have been made. Microsoft's stated goal with version 7 was to fix the most significant "bugs" and areas which caused the most trouble for developers, and then improved coverage of the standards would come later.
  • The well-known problem of having the right-hand portion of a web page cut off when the page is printed, has been fixed. Page content can also be "shrunk" to fit more text on a single page. The revamped "Print Preview" interface will also let users drag the page margins around and see the results immediately.
  • A "Zoom" selector has been added to the bottom-right corner of the user interface. Unlike the "Text size" feature, this will zoom the complete contents of the web page, allowing for easier reading on larger displays. Fonts are rendered at higher resolution.[10]
  • ClearType can be enabled or disabled separately from the rest of the operating system.[11]
  • The new "Phishing Filter" offers protection against phishing scams and other web sites that may be considered dangerous for a user to enter their personal information into. When enabled, every web site the user visits is checked against a master list of known phishing sites. If a site is listed, the user is informed. In light of the privacy implications of this feature, it is not enabled automatically; the user is asked when they start Internet Explorer 7 if they want it enabled.[12] Microsoft is working in conjunction with companies that specialize in identifying phishing schemes to ensure the list of known sites is accurate and quickly updated.[13]
  • Address Bar and status bar appear in all windows including Pop-Up which helps to block malicious sites from disguising them as trusted sites. Also the address bar features a color code to visually indicate the trustworthiness of the page. The Address Bar turns red when a page, with invalid security certificate, is accessed. In case of sistes not using any encryption, the address bar is white. And if the page uses high security certificate, the bar turns green.

Criticisms

Main article: Criticisms of Internet Explorer

Internet Explorer is subject to a relatively high volume of criticism. Much of this criticism is related to concerns about security: A notable portion of the widespread promulgation of spam, spyware, adware, and computer viruses across the Internet is known to be facilitated by exploitable bugs and flaws in the security architecture of Internet Explorer. Furthermore, a notable number of users and security experts have pointed out that Microsoft has not been sufficiently committed to fixing the browser's exploitable bugs in a timely manner, and has been ineffective in pushing those changes out to users. Several companies maintain databases of security vulnerabilities known to exist in Internet Explorer and for which no fixes have been published by Microsoft — as of June 2005, there were between 20 and 27 such vulnerabilities reported in Internet Explorer 6 for Windows XP SP2, and 146 in Internet Explorer 6 for Windows 2000 SP4.

Other criticisms, mostly coming from technically proficient users and developers of websites and browser-based software applications, concern Internet Explorer's support of open standards. Internet Explorer supports, to some degree, a number of standardized technologies, but has implementation gaps and conformance failures — some minor, some not — that have led to criticism from an increasing number of developers. The increase is attributable, in large part, to the fact that competing browsers that offer relatively thorough, standards-compliant implementations are becoming more widely used. Internet Explorer's ubiquity, in spite of its perceived inferiority in this area, frustrates developers who want to write standards-compliant, cross-browser code.

Market adoption

Usage share

Further information: Usage share of web browsers, and [[]], and [[]], and [[]], and [[]], and [[]], and [[]], and [[]], and [[]]

The adoption rate of Internet Explorer seems to be closely related to that of Microsoft Windows, as it is the default web browser that comes with Windows. Since the integration of Internet Explorer 3.0 with Windows 95 OSR 2 in late 1996, the adoption was greatly accelerated: from below 20% in 1996 to about 40% in 1998 and over 80% in 2000. This effect, however, has recently been dubbed the "Microsoft monoculture", by analogy to the problems associated with lack of biodiversity in an ecosystem. By 2002, Internet Explorer had almost completely superseded its main rival Netscape and dominated the market.

After having fought and won the browser wars of the late 1990s, Internet Explorer began to see its usage share shrink. Having attained a peak of about 96% in 2002, it has since been in a steady decline. Statistics indicate the current most significant competition comes from Gecko-based browsers, in particular Mozilla Firefox.

Nevertheless, Internet Explorer remains the dominant web browser, with a usage share of around 85% (based on statistics reference) in United States. It's relatively high in Asia, and much lower in Europe, For instance, the share is around 93% in Japan, and around 70% in Germany.[14]

Industry adoption

ActiveX is used by many public websites and web applications, including eBay. Similarly, BHOs are also used by many search engine companies and third parties for creating add-ons that access their services, for example, search engine toolbars. Because of the use of COM, it is possible to include web-browsing functionality in third-party applications. Hence, there are a number of Internet Explorer shells, and a number of applications like RealPlayer (a media player) also use Internet Explorer's web browsing module for viewing the World Wide Web within the applications.

"Standalone" Internet Explorer

While it is not officially possible to keep multiple versions of Internet Explorer on the same machine, some hackers (Joe Maddalone, Ryan Parman, et al.) successfully separated several versions of Internet Explorer making them standalone applications. These were referred as "standalone" IEs and included versions 3.0 to 5.5 SP2.

  • Multiple IEs In Windows Web Design — The web developer Joe Maddalone who found the solution.
  • Skyzyx.com - Standalone Internet Explorer — The web developer Ryan Parman who made the customized browsers files available.
  • Multiple Explorers — Downloads of all the versions

Microsoft has discontinued standalone installers for Internet Explorer to the general public. However, a blogger/web developer/programmer named Liew Cheon Fong has posted a procedure for downloading the complete install package.

  • Standalone Install Procedure for IE6 SP1

Be aware that unlike previous standalone versions of IE, running IE7 in standalone alongside a normal installation of IE6 may cause severe problems when using IE6 thereafter, owing to the insertion of at least one registry key. Some users have been unable to fix the resulting problems once IE7 has been run. It may be unwise to attempt running IE7 in standalone mode if you are not prepared for the possible consequences. See Jon Galloway's script for running IE7 more safely:

  • IE7 Standalone Launch Script

Removal

Main article: Removal of Internet Explorer

The idea of removing Internet Explorer from a Windows system was first proposed during the United States v. Microsoft case. Critics felt that users should have the right to uninstall Internet Explorer freely just like any other application software. One of Microsoft's arguments during the trial was that removing Internet Explorer from Windows may result in system instability.

An Australian computer scientist Shane Brooks demonstrated that Windows 98 could in fact run with IE files removed [15]. Brooks went on to develop software designed to customize Windows versions by removing "undesired components", which is known as 98lite. He later created XPLite to support NT based operating systems. Both of these pieces of software can remove IE after the installation of the operating system.

There are a few popular methods for removing IE from a copy of the Windows install disc so it never touches the user's hard drive. A method developed by Fred Vorck involves the manual removal of IE from installation discs. nLite, on the other hand, is an automated program that allows users to exclude IE and many other Windows components from installation as desired.

It is also not possible to run Microsoft's Windows Update with any other browser because of its use of ActiveX, therefore removing Internet Explorer will cause this.
