Windows Insiders who are opted into the Skip Ahead ring can get their hands on another new Windows 10 build today. This latest Redstone 5 release brings the build number up to version 17650 and includes Fluent Design refreshes for the Windows Defender Security Center, along with a general list of changes and improvements.

What's new

Windows Defender Security Center gets a Fluent Design refresh

  • We've heard your feedback and when you install this build you'll find we've updated Windows Defender Security Center (WDSC) to include the Fluent Design elements you know and love. You'll also notice we've adjusted the spacing and padding around the app and will now dynamically size the categories on the main page if more room is needed for extra info. Last but not least, we've also updated the title bar of the app so that it will now use your accent color if you've enabled that option in Color Settings – with Sets enabled, you will see this color in the WDSC tab.

Windows Defender Security Center

Windows Defender Firewall now supports Windows Subsystem for Linux (WSL) processes

  • You can add specific rules for a WSL process in Windows Defender Firewall, just as you would for any Windows process. Also, Windows Defender Firewall now supports notifications for WSL processes. For example, when a Linux tool wants to allow access to a port from the outside (like SSH or a web server like nginx), the Windows Defender Firewall will prompt to allow access just like it would for a Windows process when the port starts accepting connections. This was first introduced in Build 17627.

General changes, improvements, and fixes

  • We fixed an issue where File Explorer would always open with the ribbon minimized, rather than remembering how you'd left it.
  • We fixed an issue where elements on the main page of the Windows Defender Security Center app would slightly change size on mouse hover.
  • We fixed an issue where non-default languages might unexpectedly have the option to remove in Settings greyed out.
  • We fixed an issue where the Color Filters and High Contrast icons were switched in Settings.
  • We fixed an issue where clicking links in Settings that launched other apps would result in Settings crashing and nothing else happening.
  • We fixed an issue resulting in some people experiencing a Settings crash when navigating to Apps > Default Apps > Set defaults by App.

Known issues

  • On resuming from sleep, the desktop may be momentarily visible before the Lock screen displays as expected.
  • When Movies & TV user denies access to its videos library (through the "Let Movies & TV access your videos library?" popup window or through Windows privacy settings), Movies & TV crashes when the user navigates to the "Personal" tab.
  • 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.
  • 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.
  • We're aware of an issue that causes Narrator to read extra text when invoking Alt + Tab, and we're working on a fix.
  • Using arrow and Page Up / Page Down keys doesn't work to scroll webpages in Microsoft Edge. You'll need to use another input method (mouse, touch, or touchpad).
  • If you complete the setup for a Windows Mixed Reality headset on this build, the headset will remain black until it is unplugged and reconnected to the PC.

If you're a Windows Insider enrolled in Skip Ahead, you should be able to grab the new build now via Windows Update. And for more, check out Microsoft's full release notes.

  • Great will download when I get home from work in a bit
  • Why does it take months to add a tiny graphical change such as this fluent design stuff?
  • Probably not as tiny as people might think... That, and priorities...
  • What priorities. And plus, Windows 10 launched with a clusterfuck of UI inconsistencies. They remedied that slowly in time. Now they want a new design language, but they also do that half-baked, slowly, in time. I can almost guarantee their whole "Fluent Design System" implementation won't be complete when they'll want to switch to the next completely different thing.
  • It's not obvious to everyone, but one of the limitations that all app developers face (including Microsoft) is (lack of) API coverage. UWP is a new framework and is evolving rapidly. Many features (fluent design and otherwise) are available only in the latest Windows 10 releases, whereas the apps must work across the entire installed base. Developers must balance adopting new features vs. compatibility, and don't have unlimited resources to fork and maintain multiple versions of their apps. So apps (even built in ones) will always lag behind the operating system when it comes to feature adoption. This fragmentation is one why Microsoft is so hell-bent on keeping all Windows users up to date. Apple has historically had a strong advantage here because it's user base stays far more current. Over time you'll see the same benefit accrue to the Windows ecosystem as more users finally move to Windows 10.
  • I also dislike the fact that many developers don't adapt Fluent Design. Even the Windows Central app doesn't feature the newest design elements.
  • I don't blame Windows Central because remaking its app is not profitable for them.
  • True. I can see it making sense if everyone who use the app at least one or twice open the article on the web
  • Nice it also got some great animations in hamburger menu to
  • I am always cumbersome when reading Known issues lists not featuring any known issues that I am aware of, and neither having them ever read on the changes list.
  • WMR is also screwy with this build(probably due to them working on pushing out a HoloLens update). You can't use the trigger on the controllers to "laser beam select" anymore. There's just a single dot floating in the center of your view and the trigger does selection. AKA, rather than pointing with your controller to do anything, you have to move your head to place the dot then use the controller to click. Hopefully just a bug rather than the direction they are taking. Feedback posted.
  • Only 11 comments in 18 hours, looks like not many people in the insiders now with no new features appearing, there used to be 10 times these comments per hour
