Internet Explorer 11 was only available for Windows 8.1 until yesterday, but as of today anyone with Windows 7 can download and install the browser too. Although it's not the finished code, this Preview for Developers includes many of the features that will be included in the final release and are currently available on Windows 8.
Among the new features is native decoding of JPG images using the GPU in real time, which allows faster page loads and less stress on other computer components. There is also support for HTML5 link pre-fetching and pre-rendering. These two features allow developers to anticipate where you're going and have those pages ready.
If you're interested and have Windows 7 installed in your computer, you don't have to wait any longer to give Internet Explorer 11 a try. Just click here to download, either the 32 or 64-bit variant.
