Windows 10 Build 20241 released with theme-aware splash screens for apps

A new Dev build is arriving in the hands of Windows Insiders. Microsoft has pushed out Build 20241 with a few minor interface tweaks. Here's what's new in this release.

What's new in Windows 10 Build 20241

Theme-aware splash screens for apps

The splash screens of some Windows apps will now follow the app theme (dark/light). This means that if you have light theme turned on, you’ll see a light theme splash screen, and if you have dark theme turned on (for the “default app mode”) then you’ll see a dark theme splash screen. Microsoft provides the following demos of how the new feature works.

Microsoft mentions the following apps that already have this new UI in Build 20241.

• Settings
• Store
• Windows Security
• Alarms & Clock
• Calculator
• Maps
• Voice Recorder
• Groove
• Movies & TV
• Snip & Sketch
• Microsoft ToDo
• Office
• Feedback Hub
• Microsoft Solitaire Collection

In the future, more apps will receive theme-aware splash screens.

Updates to Optimize Drives page in Settings

The Settings > System > Storage > Optimize Drives has got a few changes.

• A new “Advanced View” checkbox to list all volumes including hidden volumes. It is a work-in-progress, so may not work reliable in some configurations.
• More details will appear in the “Current status” column when volumes are not available for defrag (for example, “Partition type not supported” and “File system type not supported”).
• You can now press F5 to refresh the drive list.

Updates for developers

The Windows SDK is now flighting continuously with the Dev Channel. Whenever a new OS build is flighted to the Dev Channel, the corresponding SDK will also be flighted. You can always install the latest Insider SDK from aka.ms/InsiderSDK. SDK flights will be archived in Flight Hub along with OS flights.

Changes and Improvements

• To help ensure Narrator users are aware of notifications on the screen, if a high priority notification appears while the computer is locked and stays on the screen, we will now also read it out when unlocking your PC and not just at arrival time.
• We’re removing the Japanese Address and Rinna candidate suggestion services from the Japanese IME – thank you Windows Insiders who’ve shared feedback on them.

Fixes

• We fixed an issue resulting in some Insiders experiencing APC_INDEX_MISMATCH bugchecks in recent builds.
• We fixed an issue where scrolling and pinch to zoom were not working correctly on devices with touch such as the Surface Pro X, Surface Pro 7 and others.
• We fixed an issue where selecting an IME candidate or hardware keyboard text prediction candidate was sometimes inserting the candidate adjacent to the one selected.
• We fixed an issue where new applications will fail to install with a Windows Installer service error on x86 systems.
• We fixed an issue where when attempting to perform a Reset this PC using the Keep My Files option will fail with the error, “There was a problem resetting your PC. No changes were made”.
• We fixed an issue where robocopy wouldn’t preserve the directory dates when using the move command.
• We fixed a high hitting dwm.exe crash from the last few flights.
• We fixed an issue resulting in the System Information window (msinfo32) crashing on launch.
• We fixed an issue resulting in the System Information window (msinfo32) unexpectedly having a blank icon in the taskbar.
• We fixed an issue that could result in Bitlocker encryption failing with error 0x803100b2.
• We fixed an issue resulting in flickering in certain apps when the media controls pop-up was visible on screen and you moved your mouse.
• We fixed an issue resulting in the screen flickering on certain devices when accessing the power options on the login screen.
• We fixed a recent issue where closing a tab in Microsoft Edge while Task Manager was up and running could result in Task Manager crashing.
• We fixed an issue resulting in some Insiders seeing a “Sorry, something went wrong” message when running through the workflow to improve recognition for Windows Hello Face.
• We fixed an issue from recent builds where if Settings was open when the PC went into hibernation, connected pens may fail to reconnect until Bluetooth was toggled off and back on.
• We fixed an issue that could result in Windows Sandbox showing a 0x80070003 error.
• We fixed an issue where a non-functional link to Rename your PC was displaying for non-admin users on the Projecting to this PC page in Settings.
• We fixed an issue where the Activation page in Settings would crash if you navigated to it recently while not connected to the internet.
• We fixed an issue in Printers & Scanners Settings, where clicking the Get App button available for some printers was resulting in Settings crashing recently.
• We fixed an issue where clicking the Copy button under “View hardware and connection properties” in Network Settings would result in extraneous lines saying “Proxy Auto Detect” appearing on the settings page.
• We fixed an issue impacting certain VPN connections, where clicking the entry in the Network flyout wasn’t doing anything.
• We fixed an issue that could result in Windows updates failing with error 0xc0000005.
• We fixed an issue that could result in windows.old being unexpectedly large for some Insiders.
• We fixed an issue resulting in the new gesture to control the text cursor position using the spacebar on the touch keyboard wasn’t working for some Insiders.
• We fixed an issue that could result in Internet Explorer crashing when typing certain combinations into websites with the Dayi IME.
• We fixed an issue where incorrect characters were being inserted into passwords fields when typing using the Japanese IME in Kana mode.
• We fixed an issue where when using the previous version of the Japanese IME, if you set the IME to off mode during a composition, then immediately starting typing, it could result in the underlying app crashing.

Known issues

• We’re looking into reports of the update process hanging for extended periods of time when attempting to install a new build.
• Live previews for pinned sites aren’t enabled for all Insiders yet, so you may see a grey window when hovering over the thumbnail in the taskbar. We’re continuing to work on polishing this experience.
• We’re working on enabling the new taskbar experience for existing pinned sites. In the meantime, you can unpin the site from the taskbar, remove it from the edge://apps page, and then re-pin the site.
• We’re working on a fix for an issue causing some devices experiencing a KMODE_EXCEPTION bugcheck when using certain virtualization technologies.
• We’re looking into reports where some devices are still experiencing a DPC_WATCHDOG_VIOLATION bugcheck after taking build 20236.
• We’re investigating reports that some devices are receiving a DRIVER_IRQL_NOT_LESS_OR_EQUAL bugcheck on tcpip.sys.
• We’re working on a fix where after taking build 20236 devices running Malwarebytes Web Protection are no longer able to connect to the network. Users can roll back to 20231 and pause updates or disable Web Protection as a workaround.
• We’re investigating an issue reported by some Insiders wherein the taskbar is obscuring the Power button in the Start menu. If this is happening on your PC, you may need to use the Windows key plus X menu to shutdown for the time being.
• We’re investigating GPU Compute scenarios, such as using CUDA and DirectML, not working inside of the Windows Subsystem for Linux (WSL).
• Windows Insiders on ARM PCs such as the Surface Pro X will notice that Windows PowerShell will fail to launch on this build. As a workaround, please use “Windows PowerShell (x86)” or “Windows PowerShell ISE (x86)” from the Start menu if you need to use PowerShell. Or download the new and modern PowerShell 7 which takes advantage of ARM by running natively. Plus the icon is prettier.

The Dev Channel, formerly known as the Fast Ring, reflects the latest changes made to the Windows code base. It is a work-in-progress, so the changes you see in Dev Channel releases may not appear in the upcoming feature update. So we can expect to see some features which will never appear in stable Windows 10 versions on Desktop.
Also, it is possible that Microsoft will bring some Windows 10X features to Windows 10 on Desktop. Microsoft is about to add some of Windows 10X's features to get the best of two Windows branches. The company may also replace some of the Desktop feature updates with Windows 10X releases.

If you have configured your device to receive updates from the Dev Channel/Fast Ring ring, open Settings - > Update & recovery and click on the Check for Updates button on the right. This will install the latest available Insider Preview of Windows 10.
