Windows Internet Explorer 10 ( IE10) is the next version of Internet Explorer currently being developed by Microsoft, and the successor to Internet Explorer 9.
On April 12, 2011, Microsoft released the first “IE10 Platform Preview”, which runs only on Windows 7; subsequent platform previews run on only Windows 8.
IE10 expands on Internet Explorer 9 functionality in regards to CSS 3 uptake and hardware acceleration.
On Windows 8, it will be divided into two versions with different user interfaces: a new Metro app that will not support plug-ins, and a traditional desktop application that will retain plug-in support. On 64-bit versions of Windows 8, the Metro version of IE10 will be the 64-bit version of the browser by default.
