Microsoft has released and IE11 Developer preview for Windows 7 and Windows Server 2008 R2. This is still considered a preview build which users may find a bit buggy or there could be other issues with the pre-release software, so install it with caution.
IE11 is the latest browser from the Microsoft camp and will ship with Windows 8.1 that will arrive later this year.
Microsoft has added quite a few features to IE11 including WebGL support, improved touch performance on non-touch based sites, improved keyboard navigation support, improved favorites support, and a bunch of other features that you can read about here from our IE11 preview post.
