Insider KB5074178 Windows 11 Insider Dev build 26300.7733 (25H2) - Feb. 3


UPDATE 2/09:


 Windows Insider Blog:

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 26300.7733 (KB5074178) to the Dev Channel.

Changes in Dev Channel builds and updates are documented in two buckets: new features, improvements, and fixes that are being gradually rolled out for Insiders who have turned on the toggle to get the latest updates as they are available (via Settings > Windows Update*) and then new features, improvements, and fixes rolling out to everyone in the Dev Channel. For more information, see the Reminders section at the bottom of this blog.


Changes and Improvements gradually being rolled out with toggle on*

[Built-in Sysmon]

Previously announced here, Windows now brings Sysmon functionality natively to Windows. Sysmon functionality allows you to capture system events that can help with threat detection, and you can use custom configuration files to filter the events you want to monitor. The captured events are written on the Windows event log, enabling them to be used with security applications and a wide range of use cases.


Built-in Sysmon is disabled by default and must be explicitly enabled.
  1. Go to Settings > System > Optional features > More Windows features > checking Sysmon or in PowerShell or command prompt:

    Dism /Online /Enable-Feature /FeatureName:Sysmon
  2. To complete the installation, from PowerShell or command prompt run:

    Sysmon -i
Note: If you’ve already installed Sysmon from the website, it must be uninstalled before enabling the built-in Sysmon.

Documentation will be added to Windows soon. The functionality of Sysmon remains unchanged, learn more https://learn.microsoft.com/sysinternals/downloads/sysmon.

[Voice Access]

  • Support for the Netherlands locale has been added.

Fixes gradually being rolled out with toggle on*

[File Explorer]

  • We fixed a few issues in File Explorer, including accessibility improvements (keyboard navigation and access keys), folder renaming with custom names, and missing icons/tooltips for “Add to favorites”.

[Other]

  • We fixed an issue that caused apps to freeze when working with files on OneDrive or Dropbox. Some Outlook setups with PSTs on OneDrive could also hang or reload email data.

Reminders for Windows Insiders in the Dev Channel

  • Updates are based on Windows 11, version 25H2 via an enablement package (Build 26300.7733).
  • Many features are rolled out using Controlled Feature Rollout technology, starting with a subset of Insiders and ramping up over time as we monitor feedback to see how they land before pushing them out to everyone in this channel.
  • The desktop watermark shown at the lower right corner of the desktop is normal for Windows Insider pre-release builds.
  • For Windows Insiders who want to be the first to get features gradually rolled out to you, you can turn ON the toggle to get the latest updates as they are available via Settings > Windows Update*. Over time, we will increase the rollouts of features to everyone with the toggle turned on. Should you keep this toggle off, new features will gradually be rolled out to your PC over time once they are ready.
  • Features and experiences included in these builds may never get released as we try out different concepts and get feedback. Features may change over time, be removed, or replaced and never get released beyond Windows Insiders. Some of these features and experiences could show up in future Windows releases when they’re ready.
  • Some features in active development we preview with Windows Insiders may not be fully localized and localization will happen over time as features are finalized. As you see issues with localization in your language, please report those issues to us via Feedback Hub.
  • Check out Flight Hub for a complete look at what build is in which Insider channel.
Thanks,
Windows Insider Program Team
