Windows 10 build 17046 (rs prerelease)

Windows 10 build 17046 (rs_prerelease) is the eleventh Insider Preview build of Windows 10 April 2018 Update. This build was released to Windows Insiders in the Fast Ring on 22 November 2017.

New features and changes

 * Microsoft Edge can now save and automatically fill in information in addresses and other forms found online. When you're typing in an address or other assorted forms, Microsoft Edge now asks the user if they want to save the form information. Subsequent visits to that web page can now allow the browser to generate a drop-down menu containing the information needed to complete the related fields.
 * Introduced text spacing to Reading View on Microsoft Edge. To open Reading View, go to an article or blog post and then select a book icon located next to the address bar.
 * Added a new Settings option to the Start menu's right-click context menu in the "More" submenu.
 * This build includes new and updated emoji data for over 150 languages, some of which are detailed in the official announcement.
 * Added emoji candidate support for a number of languages that previously didn't support them.
 * You can now use the emoji panel to select more than one emoji.
 * Introduced a new Tamil-language keyboard layout called "Tamil 99", as well as updating the Sinhala, Amharic and Myanmar (Burmese) keyboard layouts.

Bugs

 * VPNs that use custom pop-up windows during connection attempts may fail to connect with error 720.
 * You may not receive all of your notifications from Cortana.
 * Dynamic volumes will not mount properly or be accessible from the OS in this build. The data is still there, it is just not accessible from this build.
 * After upgrading to this build, you may lose certain dictionary files. This results in not being able to input Japanese or Simplified Chinese via the IME, Touch Keyboard, or handwriting if the OS used is a non-Japanese or non-Traditional Chinese based OS.
