4. Improvements to Microsoft Edge
"Building on strong power efficiency already available in Microsoft Edge, the Anniversary Update includes even more power-saving improvements, using fewer CPU cycles, consuming less memory, and minimizing the impact of background activity and peripheral content. Microsoft Edge lasts three hours longer than Google Chrome—long enough to finish the final movie in your favorite trilogy.
Microsoft Edge Extensions, such as Pinterest’s “Pin It Button,” Amazon Assistant, AdBlock, Adblock Plus and LastPass, will be available in the Windows Store with the Anniversary Update to add features to your browser and personalize your experience.
A new accessibility architecture for Microsoft Edge supports modern web standards, including HTML5, CSS3, and ARIA. With the Anniversary Update, page structure and content are now exposed more clearly with assistive technology. Visual presentation of web pages in high contrast mode is greatly improved to provide additional visual context, while preserving text contrast. Also, form entry when using keyboard navigation and screen readers improve in this update making the browsing experience for people of all abilities better."
