Now if you click on the Internet Explorer tile on the start screen, it would launch the desktop version Internet Explorer window, and not the full screen Internet Explorer Metro app. From its list of options, select “Set your default programs” to display a page containing a list of programs on the left.If you install a third party web browser (like Google Chrome or Mozilla Firefox) in Windows 8 and make it your default web browser, then it disables the Internet Explorer 10 app on the start screen. Touch or click it to bring up the Default Programs control panel item. The Apps results will include Default Programs. The Start screen will search apps, settings, and files for this term. To change the default browser, type “default” on the Windows 8 Start screen. If that is the case, only the desktop version of IE 10 will work. Of course, you may choose not to have IE 10 as your default browser. If the option is checked, it will open the tiles on the desktop version of IE 10. If you leave it unchecked, it will launch the Metro version of IE. You can also change which version of IE 10 runs when you click on an Internet Explorer tile on Windows 8's Start Screen. If a person checks the "Always in Internet Explorer on the desktop" option, it will always run the desktop version of IE 10, again no matter which version of Windows 8 is in use. If a person checks the "Always in Internet Explorer" option, then the Metro version of IE 10 will launch no matter which Windows 8 UI is running. However, a user can also go into IE 10's settings and change the default to one of two more choices. If you click on a link on the desktop, it will be the regular IE 10 that will be activated. So if you click on a URL in a Metro application, the Metro port of IE 10 will launch. By default, the version of IE 10 that a user will launch will depend on which Windows 8 UI is in use at the time.
In the newest entry on Microsoft's official Internet Explorer blog, IE team member Kevin Luu gives some more details about the types of launch options that will be available for IE 10 users in Windows 8. However, the web browser will be available in two different versions: one will run on the Metro user interface and will not support any plug-in programs, and the other will be the more familiar browser that will run on the desktop UI. Windows 8 will include Internet Explorer 10 among its apps.
