OS Support
Internet Explorer 10 is meant for Windows 7 SP1 and 8 only. Therefore, it does not support Windows XP , Vista or others.

Development history
Internet Explorer 10 was first announced on 2011-04-12 at the MIX 11 conference in Las Vegas. In this conference, Microsoft showcased a demo version of Internet Explorer 10 along with a demo version of Windows 8. On the same day, a Platform Preview of Internet Explorer 10 was released on the Microsoft Internet Explorer Test Drive website. It only supports Windows 7; later platform previews only support Windows 8.IE 10 Platform Preview 1 supports CSS3 grid layout, CSS3 flexible box layout, CSS3 multi-column layout, CSS3 gradient, and full hardware acceleration. Platform Preview 1 performed better than IE 9 but not always better than the competing web browsers. On 2011-09-13, Microsoft released the developer preview of Windows 8 to the general public, which came with Internet Explorer Developer Preview (the first full browser incarnation of IE 10).IE 10 was released to manufacturing along with Windows 8 and Windows Server 2012. The latter reached general availability on 2012-09-04, while the former reached general availability on 2012-10-26. A preview of IE 10 for Windows 7 and Windows Server 2008 R2 was released on 2012-11-13.

Adobe Flash Player
On Windows 8, Internet Explorer 10 includes a built-in Adobe Flash Player.Microsoft and Adobe worked together to ensure that the version of Adobe Flash included with IE 10 does not drain the battery or negatively impact performance.In the "Metro" version of Internet Explorer, only some of the features of Adobe Flash will be included for battery life, performance, and security purposes.Some features that do not work well with touch have also been removed from the "Metro" version of Internet Explorer. However, originally, not all websites can use Adobe Flash in the "Metro" version of Internet Explorer as Microsoft and Adobe maintain a list of approved websites that are, reportedly, video content, and some games.In the desktop version of IE 10, all of the features of Adobe Flash are available.On March 12, 2013, Microsoft changed this behavior from allowing only sites on a whitelist to display flash content, to allowing all sites to display flash content except those on a curated Compatibility View list (blacklist) maintained by Microsoft.

Flip Ahead
Internet Explorer 10 also introduces a new feature called Flip Ahead.This works in both Metro and desktop versions of Internet Explorer 10. It allows users to move through articles that span multiple pages as well as search results and other web pages with a "next page" or similar button. This feature is turned off by default as a user's browsing history is sent to Microsoft in order to provide the feature. Microsoft has said that some sites may need to be updated to ensure it will work as intended.

Metro UI
The Metro version of Internet Explorer 10 (available on Windows 8) includes a new UI, most of which is hidden so that the webpage being viewed takes up the entire screen.The UI can be revealed by a right click of the mouse or by a swipe from the top or bottom edges of a touchscreen.When the UI is shown, the tabs are listed on the top of the screen, with a small preview of the webpage on each tab. A button to add a new tab is placed in the top-right corner. At the bottom of the screen, the address bar and navigational buttons are shown. Navigational buttons include the Back button (to navigate to the previous page), the Refresh button (to reload active page), the Pin button (which create a new shortcut tile for the active page on the Start screen), and a wrench-shaped icon, which opens the only menu of IE10. It contains options such as "View on Desktop", which opens the current webpage on the desktop version of IE 10, and "Find on page", which can find a text string (a word, phrase, or arbitrary set of letters) in the active page.
