Microsoft, today, released the newest build to Windows 11 Dev Channel Insiders. The new build, 23545, has several fixes and improvements for File Explorer. The company says it has fixed performance issues, Apple issue, crashes and more. The taskbar search changes again. The full changelog for build 23545 is below:

changes and improvements

[Search on the Taskbar]

• Instead of providing a hover experience that opens the search box in the taskbar, we’re trying a few different experiences for when you click the search highlight in the search box instead. In some cases, clicking the lightning bolt will take you to the Bing.com search highlight page. A tooltip will always be displayed for the search highlight shine when hovering over the search box. Remember, we regularly try out different concepts and get feedback with Insiders in the Dev channel.

[Windows Share]

• We’re starting to roll out the ability to quickly give your device a friendlier name to identify sharing to and from Nearby Sharing under Settings > System > Nearby Sharing.
• We’re also rolling out the ability to see Microsoft Teams contacts (work or school) and send files to them directly within the built-in Windows Share window if you’re signed in with an Entra ID (AAD) account.

Corrections

[File Explorer]

• Fixed an issue that could cause explorer.exe to crash when closing File Explorer.
• Fixed an issue where when switching between dark and light mode (or a contrast theme) the File Explorer address bar, command bar, and context menu could get stuck in the wrong colors, making it difficult to see.
• Fixed an issue where if you launched File Explorer in a dark theme you could see a bright white flash when content was loading.
• Fixed an issue where quickly opening two File Explorer windows could cause explorer.exe to crash.
• Made a few more fixes to help improve File Explorer launch performance, including fixing a leak that would affect performance over time.
• Fixed an issue that could cause explorer.exe to crash when navigating from home.
• Fixed an issue where trying to open the gallery after adding new photos could cause a crash.
• Fixed an issue where the tab progress wheel would get stuck and show File Explorer loading a folder when loading was already complete.
• Fixed an issue where sorting changes in File Explorer would not persist in folders after navigating away and back.
• Fixed an issue that could cause icons in File Explorer tabs to be incorrect.
• Fixed an issue that caused desktop icons to become generic white icons until the desktop was refreshed.

[Taskbar]

• Fixed crash of explorer.exe with high vulnerability in the latest version that affected the reliability of the taskbar.

[Search on the Taskbar]

• Fixed an issue that caused search to sometimes not launch in recent versions of the Dev channel.

[Input]

• Fixed the problem it caused Unicode Emoji 15Support that started rolling with her Building 23475 and the updated color font format with COLRv1 Support that started rolling out with Build 23506 will no longer appear. These experiences should work again with this build.
• Did some work to help address an issue that could cause the Japanese and Chinese IME candidate windows to not appear after using connected standby, due to a crash.
• Fixed high hit tabtip.exe crash that may have affected typing ability on the last two flights.

[Settings]

• Fixed an issue where settings were not enabled in safe mode for some associates.

[Other]

• Fixed an issue where trying to take screenshots in windowed mode would take a screenshot of the entire screen instead of the app in focus for some close-ups.

Note: Some fixes specified here in Insider Preview builds from the Dev channel may make it into the service updates for the released version of Windows 11.

known problems

[Start menu]

• Some apps under All apps in the Start menu, such as PWA apps installed using Microsoft Edge, may be incorrectly labeled as a system component.

[Windows Copilot]

• We’ve heard feedback from folks on the Dev channel that the Windows Copilot preview isn’t available in some regions. We’ve found an issue and plan to re-enable it for these Insiders with a future in-flight fix.
• You can use Alt + Tab to exit Windows Copilot, but not to return to it. Windows + C will return focus to Windows Copilot
• When first starting or after refreshing Copilot using voice access, you will need to use the “Show Network” commands to click the “Ask me anything” box for the first time.
