Windows 10 Build 16251 Changes and Known Issues

Microsoft today released yet another Windows 10 Insider Preview version. Windows 10 build 16251 which represents the upcoming Windows 10 Fall Creators Update, code name "Redstone 3", is available now for Fast Ring Insiders. Here is the list of fixes and known issues.

Fixes

• We fixed an issue from the last flight where if you had display scaling set higher than 100%, you might encounter a bug where the hit targeting was offset when interacting with various parts of the shell. This was particularly noticeable in Action Center, where it might appear that nothing in Action Center could be clicked or tapped, but could also have been experienced in other UI around the system.
• We fixed an issue resulting in IMAP email accounts such as Gmail, Yahoo, and Aol potentially not syncing in the Mail app in the last two builds.
• We fixed the issue causing Windows Defender Security Center to be unable to configure and list items for Controlled folder access, Threat History and Exclusions due to a crash in the UI.
• Narrator Scan Mode is now on by default for just the Edge app. You can continue to toggle Scan Mode on and off with Caps Lock + Space. We made this change based on your feedback. Please keep providing feedback with Caps Lock + EE.
• We fixed a bug that resulting in poor text rendering on some machines when Magnifier was running with bitmap smoothing enabled. Please try it in today’s build and let us know if it seems better now.
• We fixed an issue where the Windows Defender Security Center icon appeared unexpectedly stretched out when using a wide sized tile pinned to Start.
• We fixed an issue where certain inbox apps might unexpectedly show a progress bar on their Start tiles for a short time after upgrading.
• We fixed an issue resulting in explorer.exe using an unexpectedly high amount of CPU in recent flights when certain apps such as Microsoft Edge were running.
• We fixed an issue where Groove Music’s mini view player would reset its position to default if you used File Explorer to open and start playing a new mp3 in Groove Music.
• We fixed an issue resulting in some apps, such as Tweetium, not rendering the UI correctly and becoming difficult to use.
• We fixed an issue resulting in the notification prompting you to enter tablet mode not working properly when you access in recent flights.
• We’ve heard your feedback and have adjusted the My People emoji above the Taskbar to now be referred to simply as “My People notifications”. This terminology can be found in Taskbar Settings.
• We fixed an issue where the mouse response might appear erratic on certain devices when playing games with Raw Input disabled. If you are a gamer and had noticed this issue, we’d appreciate you trying this in today’s build and letting us know if it’s improved.
• We fixed an issue where the insertion point mouse cursor appeared white for some Insiders, making it invisible against the white background of many text boxes.
• Some Insiders may have noticed the Windows Error Dialog had a new string in recent flights (“opening a portal to another dimension”). It was a placeholder while we decided what string we wanted to go with, and based on your feedback we’ve updated it to explain that the problem is being reported to Microsoft.
• We fixed the issue with PC Games using the Origin overlay where the use of overlay may cause game movement to lock up.
• TruePlay, formerly called Game Monitor, is a placeholder within the Windows UI. Your games cannot be affected at this time. We’ll have more to share soon.

Known issues

• If you installed Builds 16226-16237 and upgrade to this build, Storage Spaces will not work correctly. While Build 16241 contained a fix for the general reported issue with Storage Spaces in that build range, we discovered that the fix only applies for computers not already in the bad state, and need to do some extra work to return those already impacted to the good state. Special thanks to the Insiders that have helped us investigate this!
• Trying to use the dictation hotkey (WIN + H) in UWP apps won’t work – you’ll see the UI come up and immediately dismiss. If you’d still like to use dictation, the microphone in the touch keyboard will work. You can right-click the Taskbar for an option to show the touch keyboard button if it’s not already visible.
• We’re investigating your reports that after upgrading to the latest Insider Preview builds, some network settings are lost and revert to default settings. Static IP address configuration is reverted to DHCP. Networks which were marked as private are reverted to public. After the upgrade you will need to manually readjust your network settings back to your preferred settings.
• Start, Action Center and notification toasts may at times have a background that is 100% transparent. A fix will be available in later flight – for now, if you encounter this issue, try ending ShellExperienceHost.exe via Task Manager or rebooting to resolve the issue.
• Connecting to a VPN using a solution downloaded from the Windows Store may result in a system crash.
• The battery flyout might show unexpected text for the % charged (specifically “%1!s!%2!s!% until fully charged”).
