Today Microsoft released Windows 10 Insider Preview Build 17677 (Redstone 5) to insiders in the fast and skip ahead rings. This build introduces new features to Microsoft Edge, Narrator improvements, Kernel debugging improvements, Mobile Broadband (LTE) driver improvements, and changes to how Task Manager lists memory for suspended UWP apps.

Microsoft Edge Improvements

In this build Microsoft made some improvements to Microsoft Edge that include:

  • The settings menu is now opened with the  (“…”) button at the top of the browser. This menu has been redesigned to make it easier to find various settings and to make it clearer to see what they do.

  • Your top sites that you browse to are now listed in the Jump List on the Windows taskbar or Start Menu.
  • You can now name groups of tabs you set aside to make it more organized.

Narrator Improvements

You can now use Narrator's scan mode to select content in Microsoft Edge, Word, Outlook, Mail, and most text surfaces.

Kernel Debugging Improvements

We are adding support for IPv6 to KDNET. To make room for the larger headers required for IPv6, we’re decreasing the payload size of packets. As a result, we’re declaring a new version of the protocol, so that host PCs running the latest version of the debugger can be used to debug target PCs that only support IPv4. An updated SDK and WDK will be released soon with this support. 

Task Manager UWP Memory Reporting Changes

In prior versions, Task Manager would continue to show memory usage for suspended UWP apps.  With this version, Task Manager will no longer do that as Windows can reclaim memory from suspended apps as needed.

Mobile Broadband (LTE) Driver because the default

The Mobile Broadband driver was updated to use the NetAdapter framework in build 17655. This driver, though, was not the default and Microsoft was asking users to test it. In this build, the new Mobile Broadband driver based on the NetAdapter framework is the default mobile driver.

To see the entire release notes, you can read the this blog post. Below are the latest fixes and changes in build 17677:

General changes, improvements, and fixes for PC

  • We fixed an issue causing Narrator to read extra text when invoking Alt + Tab.
  • We fixed an issue resulting in Chinese and Japanese characters not rendering correctly in Command Prompt.
  • We fixed an issue where double-clicking text in Command Prompt only selected up to the first punctuation mark, not up to the space.
  • We fixed an issue resulting in the Home and End keys not working in Microsoft Edge in recent flights.
  • We fixed an issue resulting in a high volume of reliability issues in any XAML surface using Reveal in the previous flight.
  • We fixed an issue resulting in some apps like Adobe XD from crashing on launch in recent flights.
  • When you press F1 in Microsoft Edge it will now take you to the Microsoft Edge support page, rather than Microsoft Edge tips.
  • When a tab in Microsoft Edge is playing audio, the volume icon in the tab will now light up when you hover your mouse over it.
  • When you open local files (like PDFs) in Microsoft Edge, those files will now appear in the History section.
  • We fixed an issue where downloading files in Microsoft Edge could appear stuck on doing the security scan.
  • We fixed a recent issue where Ctrl + Shift + Left to select backwards in Notepad wouldn’t work at the end of a line.
  • When you execute “start cmd” from a Command Prompt window, a new Command Prompt tab will now be created if you have Sets enabled. This will also work for other start launches, like “start notepad”. To start something in a new window you can use the new /newwindow flag, for example “start /newwindow notepad”.
  • We fixed the issue that was preventing users from enabling Developer Mode through the For developers settings page.

Known issues

  • Important note for Windows Insider Program for Business folks: If you use your AAD account to receive new flights (via Settings > Update & Security > Windows Insider Program) there is an issue causing the “Fix me” option to be presented which unfortunately will not work and you will not be able to receive the latest flights. We’re working to fix this as soon as possible in an upcoming build. 
  • We’re working on adding dark theme in File Explorer and the Common File Dialog, but we still have some things to do. You may see some unexpectedly light colors in these surfaces when in dark mode.
  • Insiders who use Remote Desktop, project their screen, or have multiple monitors may experience explorer.exe hangs on this build. This issue can also lead to Microsoft Edge hangs.
  • If you right-click apps in the taskbar you may find that the jump list is missing pinned and recent items.
  • After update, Mixed Reality Portal will reinstall the Mixed Reality Software and as a result environment setting will not be preserved. If you need your Mixed Reality home experience to persist it is advised you not take this build until these issues are fixed.

Known issues for Sets & Office

  • Sets UX for Office Win32 desktop apps is not final. The experience will be refined over time based on feedback.
  • The top of some Win32 desktop app windows may appear slightly underneath the tab bar when created maximized. To work around the issue, restore and re-maximize the window.
  • Closing one tab may sometimes minimize the entire set.
  • Tiling and cascading windows, including features like “View Side by Side” in Word, will not work for inactive tabs.
  • The Office Visual Basic Editor window will currently be tabbed but is not intended to be in the future.
  • Opening an Office document while the same app has an existing document open may cause an unintended switch to the last active document. This will also happen when closing a sheet in Excel while other sheets remain open.
  • Local files or non-Microsoft cloud files will not be automatically restored, and no error message will be provided to alert the user to that fact.
