Microsoft released Windows 10 Insider Preview build 17639 to Insiders on the Skip Ahead subset of the Fast ring today, bringing with it improvements to Sets, Bluetooth settings, and Calculator. The build is from the Redstone 5 development branch, so it's a preview of the feature update that won't arrive until this fall.
Along with the new features, as usual, there's a list of fixes, improvements, and known issues. Here's what got fixed and improved:
We fixed an issue resulting in duplicate entries in Disk Management.
We fixed an issue that could result in certain UWP apps silently terminating when minimized.
We fixed an issue resulting in certain devices with BitLocker enabled unexpectedly booting into BitLocker recovery in recent flights.
We fixed a race condition that could result in the taskbar not autohiding after opening and closing the Start menu while a fullscreen window was visible.
We fixed an issue where typing in Start would switch to a blank Cortana screen if Start was open when the PC went to sleep.
We fixed an issue when using Arabic as your display language where after using the X to close the touch keyboard in a UWP app text field it might stop coming up automatically in that field.
Sometimes having too many choices can be confusing and less is more. That is why this new build has consolidated the places where users can adjust their display brightness by removing the display brightness slider in Control Panel Power Options and the “Display brightness” section under Power Options Advanced Settings. Don’t worry! You can still adjust your display brightness via Settings > System > Display settings, the Action Center, and via keyboard hot keys.
Here are the known issues:
- If you open Settings and clicking on any links to the Microsoft Store or links in tips, Settings will crash. This includes the links to get themes and fonts from the Microsoft Store, as well as the link to Windows Defender.
- 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.
As always, it's worth reading the known issues before installing a preview build of Windows 10. For example, the desktop being visible before the lock screen appears is a security issue, and you'll want to be aware of that.
Redstone 5 still has a long way to go, but this might be the last build that shows up in Skip Ahead. With the release of Redstone 4 just weeks or even days away, Redstone 5 builds will start showing up in the standard Fast ring sooner rather than later.
If you're opted into Skip Ahead, you can grab today's build by heading to Settings -> Update & security -> Windows Update -> Check for update. If you're not, you can always try to enroll via the Windows Insider Program tab, although space is limited, so it might not work.
