Microsoft has released Windows 11 Insider Preview Build 26220.7752 (KB5074177) to the Beta Channel, introducing built-in Sysmon functionality and several important improvements for Windows Insiders.
Built-in Sysmon Arrives in Beta Channel
Windows now brings Sysmon functionality natively to the operating system. This powerful feature allows users to capture system events that can help with threat detection, using custom configuration files to filter specific events for monitoring. The captured events are written to the Windows event log, enabling integration with security applications and supporting a wide range of use cases.
Built-in Sysmon is disabled by default and must be explicitly enabled:
- Go to Settings > System > Optional features > More Windows features > checking Sysmon, or use PowerShell/command prompt:
Dism /Online /Enable-Feature /FeatureName:Sysmon
- To complete the installation, run:
sysmon -i
Important: If you have already installed Sysmon from the website, it must be uninstalled before enabling the built-in version.
Voice Access Expands to Netherlands
Support for the Netherlands locale has been added to Voice Access, expanding the feature's availability to more users across Europe.
Critical Fixes and Improvements
File Explorer
Microsoft has addressed several File Explorer issues, including:
- Accessibility improvements (keyboard navigation and access keys)
- Folder renaming with custom names
- Missing icons/tooltips for "Add to favorites"
OneDrive and Dropbox Integration
A significant issue causing apps to freeze when working with files on OneDrive or Dropbox has been resolved. This fix also addresses problems where some Outlook setups with PST files on OneDrive could hang or reload email data unexpectedly.
About the Beta Channel
This update is based on Windows 11, version 25H2 via an enablement package. Features are rolled out using Controlled Feature Rollout technology, starting with a subset of Insiders and gradually expanding.
Windows Insiders who want early access to features can turn ON the toggle to get the latest updates as they become available via Settings > Windows Update.
