[10] On November 13, 2012, Internet Explorer 10 and the Platform Update were made available for download to all users.

While Don Reisinger of eWeek listed his requested features for the next version, Michael Muchmore of PC Magazine tested Platform Preview 1's performance and HTML5 support with both Microsoft's and third parties' test suites.

In his test, Platform Preview 1 performed better than Internet Explorer 9 but not always better than the competing web browsers.

[24][25] On September 13, 2011, Microsoft released the developer preview of Internet Explorer 10 to the general public (the first full browser incarnation).

[35] 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.

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 (CV) list (blacklist) maintained by Microsoft.

The Metro version of Internet Explorer 10 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.

It contains options such as "View on Desktop", which opens the current webpage on the desktop version of Internet Explorer 10, and "Find on page", which can find a text string (a word, phrase or arbitrary set of letters) in the active page.

Internet Explorer 10 is the first web browser to support smooth CSS transitions of linear gradients.

Internet Explorer 10 no longer features or supports the following:[45] At the Windows Phone Developer Summit in June 2012, Joe Belfiore announced Windows Phone 8 due towards the end of 2012, which will include a mobile version of Internet Explorer 10 that offers four times faster JavaScript performance and two times more support for HTML 5 features.
