How do I install Internet Explorer 10 on Windows 8?

Internet Explorer 10 is preinstalled with Windows 8. No additional action is required.

How does Internet Explorer 10 integrate with Windows 8?

Internet Explorer 10 is the default handler for the HTTP and HTTPS protocols and the default browser for Windows 8. There are two experiences in Windows 8: Internet Explorer and Internet Explorer for the desktop. Internet Explorer is the default browser for touch-first, immersive experiences. Internet Explorer for the desktop provides a more traditional window and tab management experience. The underlying platform of Internet Explorer 10 is fully interoperable across both Internet Explorer and the familiar Internet Explorer for the desktop, enabling developers to write the same markup for both experiences.

What operating systems does Internet Explorer 10 run on?

Internet Explorer 10 is supported on the following operating systems and platforms:

• Windows 8

• Windows Server 2012

• Windows 7 SP1

• Windows Server 2008 R2 with SP1

Which security features are new or improved in Internet Explorer 10?

Internet Explorer 10 supports enhanced memory protection and the HTML5 sandbox attribute, as well as Enhanced Protected Mode.

The HTML5 sandbox attribute enables security restrictions for iframe elements that contain untrusted content. These restrictions enhance security by preventing untrusted content from performing potentially malicious actions. For more information, see HTML5 sandbox attribute on the Internet Explorer Developer Center.

Enhanced Protected Mode provides additional security. It's enabled by default in Internet Explorer, and can be enabled for Internet Explorer for the desktop through Group Policy and Internet Options on the Tools menu.

What privacy features are new or improved in Internet Explorer 10?

The privacy features in Internet Explorer 9 persist in Internet Explorer 10, including Tracking Protection functionality, which helps protect users from being tracked online or when using the InPrivate browsing mode.

What improvements does Internet Explorer 10 provide in supporting modern web standards such as HTML5?

Internet Explorer 10 demonstrates our commitment to an interoperable web by supporting modern web standards. Doing so enables developers to use the same markup across web browsers, helping to reduce development and support costs. Modern web standards that Internet Explorer 10 supports include:

• HTML5 (Asynchronous script execution, AppCache API, channel messaging, drag-and-drop APIs, history, parsing, Sandbox, Spellcheck, video, Web Workers, WebSockets).

• Cascading Style Sheets, Level 3 (Advanced Layout, Visual Effects, Panning and Zooming, Removal of Style Sheet limits).

• Document Object Model (advanced hit-testing APIs, media query listeners, XMLHttpRequest enhancements, and pointer and gesture events).

• Indexed Database API.

• Scalable Vector Graphics (SVG, filters).

For more information about specific changes and additions, see the Internet Explorer 10 Guide for Developers.

Yes. You can review the XML-based compatibility list.

Are browser plugins, such as Silverlight, supported in Internet Explorer 10?

Internet Explorer provides an add-on–free experience, so browser plugins don't load and dependent content isn't displayed. However, Internet Explorer for the desktop does support browser plugins, including ActiveX controls such as Adobe Flash and Microsoft Silverlight. See the IE blog, Browsing Without Plug-ins, for more information.
