By default, the Windows 8 consumer preview opens the appropriate version of IE to your current use environment. That is, if you are currently running a Metro application, the link will open in Metro version IE10, and if you are running a desktop application, the link will open in the desktop version of IE10.
If you don't like the solution above, you can define it yourself. In the IE Properties dialog box, you can change the settings in the "Programs" tab.
The way you change settings is simple, you can enter keywords such as "link", "Default" or "program" in the Start Screen search box, for example, the following is the result of searching for "default":
IE10 as the default browser offers both Metro and desktop editions, and if IE is not the default browser and you still want to use IE10 to open links in other programs, you can only use the desktop version of IE10, and you won't be able to make the changes above. When IE10 is not the default browser, the "Choose how to open Links" option in the IE Property "program" is disabled.
How do I quickly select a default browser? In the Windows 8 Start screen, enter "Default", the Start screen will search for applications, settings, files, etc., in the application of search results, will include the default program, access to the default control Panel, you can choose Internet Explorer or other browsers , and set it to the default.
Conclusion
IE10 provides you with a full-screen, immersive website experience. We find that a lot of people--even the most enthusiastic and intense browsing patterns--prefer Metro style browsing because it reduces manual operations less and makes you more focused on what you're browsing. Still, for some browsing, desktop version IE continues to play an important role. The browser's default startup settings allow you to change to the "halfway" experience.
