This new version of the Microsoft® Windows® operating system also includes a new version of Microsoft Windows Internet Explorer®, which is called Internet Explorer 10. Internet Explorer 10 on Windows 8 comes in two different versions:
The touch-optimized version of Internet Explorer runs inside of the new Windows UI. Compared to the desktop browser, the browser in the new Windows UI has a much simpler interface that is focused on just the core browsing scenarios. Many of the features that exist in desktop Internet Explorer are not implemented in the touch-optimized version of Internet Explorer, including things like support for add-ons like toolbars and browser extensions.
Figure 1: Touch-optimized version of Internet Explorer
Because the touch-optimized version of Internet Explorer is a Windows Store app, it runs in full screen at all times (unless snapped). The default view shows the web page on the entire display. Swiping from the top or bottom edge of the screen or right-clicking will reveal the navigation controls for Internet Explorer at the bottom and thumbnails for all of the web pages that are currently loaded in the tab bar at the top.
Tabs are supported in the touch-optimized version of the browser, but the implementation is not the same as the desktop browser. If you wish to open a new tab in the new browser, swipe from the top or bottom or right-click, and then click the plus sign at the right end of the tab bar.
Figure 2: Plus sign at right end of bar
This will open a flyout at the bottom of the screen with a list of your frequently accessed sites, pinned sites, and favorites. You can type an address or search term in the bar at the bottom or select any of the tiles on the screen to navigate to a web page.
Figure 3: Flyout with frequently accessed sites, pinned sites, and favorites
Below the new tab button on the tab bar is a button with a circle and three dots. Clicking this button will reveal a menu below with additional options you can use for working with tabs.

As we can see with the diagram below, Internet Explorer 10 has distilled the number of commands that are exposed to the user down to just those that are core to the browsing experience.
Figure 5: Internet Explorer Address Bar options
Pinning a website creates a secondary tile on the Start Screen that is linked directly to that site. With site pinning, you can personalize your Windows Start screen with the sites you use all the time. You can pin any website to the Start screen from Internet Explorer 10, so you have one place to access all the things you care about or need.
The tiles for pinned sites reflect the site's color and icon. Web sites can provide higher resolution PNG file site icon and specify the tile background color. With Internet Explorer 10, sites can provide background notifications for new messages and other account activity on the website.

It also places a link to the site in the list of Pinned sites shown in the flyout that appears when you select the address bar.
Figure 7: Pinned sites in navigation bar flyout
The site can also program additional commands that appear in Internet Explorer navigation bar in a touch-friendly way, the same way that sites can program jumplists for Internet Explorer on the desktop.

Integration with the Store makes it easy to discover and launch Windows Store apps for the sites you visit in Internet Explorer. When you open a site that has an app in the Windows Store, the Tools icon is updated with a plus sign to tell you when there is something "special" about the page. You can tap on it to go to the store to install an app. Once an app is installed, you can launch it directly from the site. For example, here is WordPress.com in Internet Explorer 10.
Figure 9: Site displays notification that app is available
Internet Explorer 10 knows that an app is available for a specific site because the site has added marked to their HTML to indicate this. In the WordPress example, you can see the following code has been added to their site.
<meta name="msApplication-PackageFamilyName" content="AutomatticInc.WordPress.com_9ejavqh8rasr8"/>
<meta name="msApplication-ID" content="App"/>
Snap makes it easy to use Windows 8 for more than one thing at a time. You can browse in Internet Explorer 10 and have side-by-side access to your mail, music, or any other application. The browser adapts to the narrow "snap" size and automatically undocks when necessary for user interaction. All of the core browsing capabilities are available when snapped – panning, pinch and double-tap zooming, and following links. Web sites will also have the ability to provide an optimized experience when it detects that it is being displayed in the Snapped view.
Figure 10: Multitasking with Windows 8 "snap" lets you put your site side-by-side with other applications like the Messaging app.
Charms provide a consistent way to perform common actions like searching and sharing in Windows 8. Internet Explorer 10 supports the Search, Share, Devices, and Settings charms.
Figure 11: The charms appear when you swipe in from the right edge, press Windows key+C, or move your mouse to the bottom or top-right corner of the screen.
For the Search charm, Internet Explorer 10 uses the default search engine, which you can set in Manage Add-ons in the desktop browser. After initiating a search in the charm fly-out, search results are shown as you type, including the same picture and instant results you see in Internet Explorer on the desktop, if your search engine supports them.
With the Share charm, you can access any application that supports sharing (like Mail). This allows you to send a rich link preview with image, description, and hyperlink so it's easy to share more than just a link.
Figure 12: Internet Explorer 10 and Mail support sending rich link previews with image, description, and hyperlink
The Devices charm makes printing easy and consistent. You can print from any webpage from Internet Explorer – handy for things like airline boarding passes – by tapping or clicking the Devices charm and selecting a printer.
The Settings charm provides quick access to the most frequently used configuration settings for Internet Explorer 10. You can quickly clear browsing history, control location access, and more. Only the most commonly used settings are displayed here, but when you need access all of the available settings, Internet Options is still available with the desktop browser. Many of the settings in Internet Options will apply in both versions of the browser.

Flip Ahead enables users to fluidly page between web content by simply swiping to the next page. When a user is viewing a page that is part of a sequence (such as a five page New York Times article, images in a slideshow, or blog posts), they can Flip Ahead to the next page in the article, the next image in a slideshow or the next post for the blog. We refer to these behaviors collectively as Next Page. When a user is not in paginated sequence, they can Flip Ahead to other "related" content on the site. We refer to this behavior as Next Article. The overall experience will be similar to flipping through a magazine or catalog.
The term Flip Ahead is used to describe either Next Page or Next Article where either would be appropriate.
Flip Ahead provides an iconic touch-optimized experience for the touch-optimized version of Internet Explorer, but it supports mouse and keyboard as well. Flip Ahead does not replace or interfere with the existing Back and Forward navigation. Flip Ahead will only be available when there is nothing otherwise available on the Forward stack.
<a type="next" href="http://foo.bar/nextpage/"> (html5 only)
<link rel="next" href="http://foo.bar/nextpage/">
The feature is powered by a set of client-side rules, updated via a service. Bing provides the service and rule generation. In order to inform this rule generation and help us scale out coverage, Internet Explorer collects user clicks, site visits, and DOM information. Because this feature gathers data about its usage, Flip Ahead is disabled by default. You can enable it from the Settings charm.
Figure 14: Enable Flip Ahead
Traditionally add-ons have been a large contributor to performance and stability problems for Internet Explorer, so in order to help ensure the best possible experience on the modern web, these add-ons are not supported in the touch-optimized version of Internet Explorer. This includes all add-ons like ActiveX® Controls (Silverlight), toolbars (Bing Bar), and browser helper objects (Skype click to call) and applies both to add-ons from Microsoft as well as from third parties, with the exception of Adobe Flash, which receives special handling in Windows 8. More information about Adobe Flash in Internet Explorer 10 is provided below.
Microsoft® believes that the best experience for websites that previously required add-ons in order to function will be provided through Windows Store apps for those sites.
The desktop browser will continue to allow add-ons as it always has. If a user sees that the site they are accessing does not function properly in the touch-optimized version of Internet Explorer because it requires add-ons, they can use the option to View on the desktop from the page tools (wrench) menu.
Figure 15: View on the desktop option
Developers can help ensure their users have the best experience by adding a tag to their site indicating the ActiveX controls are required. If a user navigates to one of these sites, they will see a prompt indicating that a plug-in is required in order to use the site. To address this issue, the touch-optimized version of Internet Explorer has an app command for Use Desktop View. This will open the currently viewed page in the desktop browser where plug-ins continue to be supported.
Figure 16: Site uses add-ons that require desktop browser
For more information on our handling of add-ons in Windows 8, please see the following article.
Web Sites and a Plug-in Free Webhttp://blogs.msdn.com/b/ie/archive/2012/01/31/web-sites-and-a-plug-in-free-web.aspx
By default, Windows Store apps are suspended whenever they are not in the foreground which means that things like audio playback will not work once you switch away from the app. If the app needs to support background audio, they can register for this capability and Windows will handle playing the audio stream in the background for the app. Internet Explorer 10 does not support this background audio capability, so you will see that when you switch away from Internet Explorer while audio is playing, the audio will stop. Stopping audio playback when you switch away from Internet Explorer will prevent unwanted background sounds such as those from advertisements playing back when Internet Explorer is not on the screen, but it will also prevent you from playing music from the web in the background as well.
There are three possible workarounds that you can use to address this if it is causing a problem for your customer.
This section calls out additional information that you should know about the touch-optimized version of Internet Explorer.
Internet Explorer for the desktop builds on the UI changes that were introduced in Internet Explorer 9 while integrating with the visual style of Windows 8, and as a result it looks very similar to the previous version of Internet Explorer. There are no significant feature updates for this version of the browser from a consumer support perspective.
Figure 17: Desktop version of Internet Explorer 10
In the default configuration, the version of the browser that will launch when clicking the Internet Explorer icon or clicking a link will depend on where you were when you launched the browser.

The behavior described earlier is the default behavior, but it can be changed in the Programs tab of Internet Options.
Note: For more information about changes to setting the default browser in Windows 8, please see the Changes to the Desktop module.
Figure 18: Configure how Internet Explorer opens
The drop-down menu has three options:
Figure 19: Choose how you open links
None of the above options affect how pinned site tiles on the Start screen will open. By default, pinned sites will always open in the touch-optimized version of Internet Explorer, though this can be changed by selecting the Open Internet Explorer tiles on the desktop check box shown earlier.
The touch-optimized version of Internet Explorer is only available if Internet Explorer 10 is set as the default browser. If a user installs a third-party browser and sets it to be the default, the Internet Explorer tile on the Start screen will be replaced with a tile that opens the desktop version of Internet Explorer 10.
Table 2: Different tiles displayed if Internet Explorer is not the default browser
Internet Explorer is the default browser
Internet Explorer is NOT the default browser
In order to regain the ability to access the touch-optimized version of Internet Explorer, the user will need to set Internet Explorer back to the default browser.
After setting a third party browser to be the default, previously pinned sites will open in the desktop version of Internet Explorer.
Windows 8 includes a new power-optimized, touch-friendly version of Adobe Flash Player. Adobe Flash content on compatible Web sites will now play in Internet Explorer 10 in the new Windows UI. The touch-optimized version of Internet Explorer 10 with Flash on Windows 8 enables people to see more of the Web working with high quality, especially compared with the experience in other touch-first or tablet experiences.
Because some popular Web sites require Adobe Flash and do not offer HTML5 alternatives, Adobe and Microsoft worked together closely to deliver a Flash Player suitable for the new Windows Experience.
Both Internet Explorer 10 on the Windows desktop and the touch-optimized version of Internet Explorer use the same integrated Flash Player, with no need to download or install an additional player.
While any site can play Flash content in Internet Explorer 10 on the Windows desktop, only sites that are on the Compatibility View list can play Flash content within Internet Explorer in the new Windows UI. We place sites with Flash content on the Compatibility List if doing so delivers the best user experience with those sites.
A good Flash Player experience is part of a no compromise experience across all form factors of PCs, including touch-centric PCs running Windows 8. We've heard feedback from customers about their experience with sites that do not offer an HTML5 experience. Many sites require Flash in order to function and some sites offer a HTML5 experience but still deliver their best experience with Flash, such as youtube.com.
The Flash Player included with Windows 8 is based on the full PC implementation and not a limited mobile subset, and it will be made available on the new chip architectures that Windows 8 supports. Adobe is committed to delivering this same Flash Player support for Internet Explorer on both x86/64 and the initial delivery of Windows RT PCs (Windows running on ARM processors).
Adobe Flash is now being distributed along with Windows, so there is no longer a need to separately download and install Flash on Windows 8 PCs. Attempting to download Flash from Adobe's website will display a warning indicating that Flash is built into Windows. Attempting to install Flash using the installer from Adobe.com will also fail.
Figure 20: Notification displayed when you attempt to install Flash on Windows 8.
Now that Flash is being distributed as part of Windows, it will also be updated as part of Windows, which means that it will be updated through Windows Update.
Adobe Flash in the touch-optimized version of Internet Explorer will not be enabled for all sites. Instead, Internet Explorer will use the Compatibility List to determine which sites it will be enabled for, which will include sites that are known to provide a poor experience without Flash. Internet Explorer uses the Compatibility List to change the way that sites are rendered by changing attributes like the user agent string that is reported or the DOCMODE that is used to render the page.
You can view the list of sites where Flash is enabled on the touch-optimized version of Internet Explorer 10 by looking at the Compatibility List. This file is located at the path below.
Scroll down to the bottom and look for the section labeled <Flash>. You can use this list to identify which sites Flash should work with and which it should not when using the touch-optimized version of Internet Explorer.
When troubleshooting a webpage in Internet Explorer, it is important to understand what is being used to actually display the content on the site. While traditionally the majority of interactive and video content on the web has used Flash, with the advent of HTML5 Video and HTML5 Canvas tag, it may not be immediately obvious when a site is using a plug-in for its content.
One way to tell if Flash is in use on a particular page is by right-clicking on the video or interactive element on the page and seeing which options are available. If Flash is in use, a context menu will appear, and if you scroll to the bottom of that menu, it will display About Adobe Flash Player.
Figure 21: Adobe Flash Player in context menu
Right-clicking on an HTML5 video in the touch-optimized version of Internet Explorer 10 will not yield a context menu.
Right-clicking on an HTML5 video in Internet Explorer 10 on the desktop will display the following context menu. This menu may be customized by the site, but it will not display Adobe Flash Player at the bottom.
Figure 22: HTML5 Video Controls
Adobe will provide support for Flash related issues, but we still have the ability to disable it through Manage Add-ons if needed.

Web browsers store information to make it easier and faster for you to log on to websites or to make recommendations. But when you browse the web on a public network (or even at home), you might not want to store information such as passwords or search and webpage history.
If you use an InPrivate tab to browse, Internet Explorer 10 will delete your passwords, search history, and webpage history when you close the tab.
With Internet Explorer 10, Do Not Track is enabled in the "Express Settings" portion of the Windows 8 setup experience. The websites you visit often contain content from third parties. In order to load this content, certain information about your computer is sent to each of the third parties. With the Do Not Track feature built into Internet Explorer, you can send a signal to marketers and websites requesting them to not collect data that enables them to track you on the web.
Sometimes it's hard to tell whether or not a site is legitimate. SmartScreen helps you identify known phishing and malware sites and helps you make informed decisions about app downloads.
