What's new in Microsoft Edge on Windows 10 build 16226

This is the latest release, which is available for Windows Insider Preview (Fast) Desktop

New Microsoft Edge features

New in Windows 10 build 16226

New features in Microsoft Edge:

  • Giving you more control over closing tabs: We’ve updated Microsoft Edge to ensure the X in the tab band is always available to close a tab, even when a JavaScript (i.e. alert, prompt, etc.) dialog is showing within Microsoft Edge. Additionally, closing the Edge window always remains an available option. You can also access many browser capabilities (i.e. favorites bar, settings, etc.) while a dialog is showing.
  • Making it easier to move from another browser: Users can now migrate Cookies and Settings from Chrome to Microsoft Edge, which will make it easier for users to make the move to Microsoft Edge as their primary browser.

Improvements to EPUB reading:

  • Copy and Ask Cortana: Now, when you select your text, you can Copy and Ask Cortana in addition to adding notes, highlighting and underlining. Cortana can help you do a little research while you’re reading an EPUB book.

  • Books roamed across devices: Your books from the Windows Store are available on your Windows 10 devices, and your reading progress, bookmarks, and notes are kept in sync.

Improved Favorites experience:

  • New experience when saving new favorites: You can now view your favorites as a directory tree when you save new favorites, and collapse or expand folders from within the “Add to favorites” dialog. Just click the “Save in” folder list to get started!

Pin your favorite websites to the taskbar: Pinned sites are back! We heard your feedback, and are in this build you can now pin a website to the taskbar from Microsoft Edge! We’ll use the site’s icon to give you quick access to your favorite sites right from the taskbar. Simply select “Pin this page to the taskbar” from the settings menu in Microsoft Edge.

Microsoft Edge PDF improvements: We’ve added more highlight colors and the option to Ask Cortana in PDFs in Microsoft Edge.

Other improvements:

  • Microsoft Edge’s splash page (seen when newly launched) so that the color transitions more smoothly to the Start and New Tab pages.
  • You will now be able to close the Microsoft Edge app directly using the close button, even when a JavaScript dialog is showing.
  • We’ve added an option to “Add tabs to favorites” from the right-click context menu on tabs. Using it will create a Favorites folder with all the sites open in tabs in the current window.
  • New tabs will now animate more smoothly onto the tab bar when opened and closed.
    We’ve improved session restore behavior so that when a multi-window Microsoft Edge session is restored by clicking on a link (for example, from an email), the window in focus at the end of restoration is the one containing the new link.

  • PDF Annotations: The Web Note annotation feature now works in PDFs as well as web pages. You can use the “Make a Web Note” button on the top right of browser frame to invoke an annotations bar. Using different modes in the annotations bar, you can ink on the PDF, highlight text and erase your annotations. You can save the work onto the PDF file for later use.
