Users whose accounts are configured to have fewer user rights on the system could be less...

Internet Explorer 11 helps overcome the effects of network latency, making every day browsing feel fast and responsive without hurting battery life, CPU, network bandwidth, or memory. Network latency is a problem that holds back Web performance, even though we enjoy more bandwidth now than ever before. IE11 reduces the effects of network latency by downloading and preloading pages and Web resources in the background, downloading multiple resources in parallel using the SPDY/3 protocol, and prioritizing...

Today, we submitted a new proposal to the W3C, CSS Scrolling Snap Points, designed to enable fast and fluid panning experiences for touch and other input devices, based on APIs introduced in IE10 and improved in IE11. These APIs enable developers to more easily build panning experiences such as paginated content and scrolling photo galleries that are perfect for touch and work just as easily with mouse, keyboard, or trackpad. A great example of this experience is the MSN homepage optimized for Windows...

Business and organizations that want to manage their own update schedule can use the IE11 Automatic Update Blocker Toolkit to disable automatic delivery of Internet Explorer 11. This Blocker Toolkit—like its predecessors for IE10, IE9, IE8, and IE7—is now available on the Microsoft Download Center. While we encourage all customers to upgrade their browser to the latest version as quickly as possible, this approach enables organizations to control when they are ready to deploy IE11 to their Windows...
