After 26120.961 did not work out as Microsoft had imagined, a new update is now available for Dev Insiders. KB 5038603 increases the version number of Windows 11 24H2 to 26120.1252. This is more of a correction version. In addition, the blocked new functions are reactivated.

Known issues with KB5038603

  • [WICHTIG] Windows Insiders joining the Development Channel on PCs running Windows 11, version 24H2 Build 26100.xxxx will see a note saying “(Repair Release)” next to the latest Development Channel build from Windows Update. This is nothing to worry about, as it simply means that an in-place upgrade is being performed to update your PC to the latest build in the Development Channel.
  • NEW There is an issue in this build where the Windows Update page in Settings doesn't display correctly (no text is displayed) for Insiders who use certain languages. If you're affected by this, the update should still happen on its own with the next build, but you may have to wait a bit.
  • New: Adding additional languages ​​or optional features may fail with error 0x800f081f.
  • Task Manager: Navigating between different pages in Task Manager may cause Task Manager to crash.

Corrections and improvements made by KB5038603

  • We're starting to re-enable the new features that we started enabling on 6/28 but paused on 6/30. We're starting to enable these features on a small percentage basis first, so not all Insiders in the Dev Channel who have this switch enabled will see all of these features right away. And some features may appear while others may not appear yet.
  • Start menu You can now also pin applications from the Start menu to the taskbar by dragging items directly from the pinned section in the Start menu to the taskbar. See also this post
  • File Explorer: The ability to drag and drop files between breadcrumbs is now available in the File Explorer address bar – thanks again to Insiders who shared their feedback on this feature!
  • Lock screen We're starting to bring weather and more to your lock screen with this build in the Dev Channel. Stay informed and efficient with dynamic updates that bring finance, traffic, and sports to your lock screen in addition to weather. Maps design has been improved with acrylic blur, map size, spacing, and font optimization. To enable this feature, go to Settings > Personalization > Lock screen. For more info, see Personalize your lock screen.
  • Widgets We're also making some improvements to the Widgets button on the taskbar so that the icons on the taskbar are clearer, and we're also introducing a larger set of animated icons.
  • Corrections:
  • Fixed an issue that caused some Insiders to see a bugcheck with the KERNEL_SECURITY_CHECK_FAILURE error in recent builds.
  • Fixed an issue believed to be causing some Insiders to recently notice dropped frames in some animations, particularly in Task View.
  • File Explorer Fixed an issue that could cause explorer.exe to crash when navigating away from the home page.
  • Input:

  • Fixed an issue that caused a cyclical crash on input for a small number of Insiders in the latest build, impacting various input experiences.
  • Fixed an issue where the Input Method Editor (IME) candidate list might not appear or might appear in the wrong location.
  • Fixed an issue that caused Insiders to experience errors when attempting to use voice typing with certain languages, such as Chinese.

  • Fixed an issue that caused the preferred audio volume (set in Settings > System > Sound > Volume Mixer) for Microsoft Edge to not be retained when the app was restarted.
  • This update updates Country and Operator Settings Asset (COSA) profiles for certain mobile operators.
    Fixed an underlying issue that caused some Insiders to see a Pcasvc.dll error dialog with the message “Missing entry: PcaWallpaperAppDetect” after upgrading from Windows 11 version 22H2/23H2 to a 26xxx build.
