Microsoft has released Windows 11 Insider Preview Build 26300.7733 to the Dev Channel, introducing several significant improvements including native Sysmon functionality, expanded Voice Access support, and important fixes for File Explorer and cloud storage integration.
What's New in Build 26300.7733
This release represents a major step forward for Windows 11, particularly for IT professionals and security-conscious users who rely on advanced system monitoring capabilities. The update is delivered through KB5074178 and is based on Windows 11, version 25H2 via an enablement package.
Built-in Sysmon: A Game-Changer for Security Monitoring
What is Sysmon?
System Monitor (Sysmon) is a Windows system service and device driver that monitors and logs system activity to the Windows event log. It has long been a valuable tool for security professionals, providing detailed information about process creations, network connections, and changes to file creation time.
Native Integration Benefits
Previously, Sysmon was available as a separate download from Microsoft Sysinternals. With Build 26300.7733, Windows brings Sysmon functionality natively to the operating system, offering several advantages:
Simplified Deployment: IT administrators no longer need to download and deploy Sysmon separately across their organizations. The built-in version can be enabled directly through Windows features.
Official Support: As a native Windows component, built-in Sysmon benefits from official Microsoft support and integration with Windows Update for patches and improvements.
Standardization: Organizations can rely on a consistent Sysmon implementation across all Windows 11 devices without worrying about version discrepancies.
How to Enable Built-in Sysmon
Built-in Sysmon is disabled by default and must be explicitly enabled. Here's how to activate it:
#### Method 1: Settings Interface
- Navigate to Settings > System > Optional features
- Select "More Windows features"
- Check the box for "Sysmon"
- Complete the installation
For administrators who prefer command-line deployment:
powershell
Dism /Online /Enable-Feature /FeatureName:Sysmon
After enabling the feature, complete the installation by running:
powershell
sysmon -i
Important Considerations
If you've already installed Sysmon from the Sysinternals website, it must be uninstalled before enabling the built-in version. This prevents conflicts between the two implementations.
The functionality of Sysmon remains unchanged from the standalone version. Users can continue to use custom configuration files to filter events and tailor monitoring to their specific needs. Captured events are written to the Windows event log, enabling integration with security information and event management (SIEM) systems and other security applications.
Enhanced Voice Access Support
Netherlands Locale Now Supported
Build 26300.7733 expands Voice Access capabilities with support for the Netherlands locale. This addition demonstrates Microsoft's commitment to making accessibility features available to users worldwide.
Voice Access allows users to control their PC and author text using voice commands, providing an essential accessibility tool for users with mobility impairments and offering an alternative input method for all users.
The Growing Voice Access Ecosystem
With each new locale addition, Voice Access becomes more useful for international users. The Netherlands joins a growing list of supported languages, making Windows 11 more accessible and user-friendly across diverse markets.
Critical Fixes for File Management
File Explorer Improvements
Microsoft has addressed several issues affecting File Explorer functionality in this build:
Accessibility Enhancements: Improved keyboard navigation and access keys make File Explorer more usable for users who rely on keyboard-only navigation or assistive technologies.
Folder Renaming: Fixed issues with folder renaming when using custom names, ensuring that user-defined folder names are properly applied and maintained.
Favorites Icons and Tooltips: Resolved problems where icons and tooltips for "Add to favorites" were missing, improving the user experience when organizing frequently accessed locations.
Cloud Storage Integration Fix
One of the most impactful fixes in this build addresses an issue that caused applications to freeze when working with files on OneDrive or Dropbox. This problem affected productivity for users who rely on cloud storage as their primary file management solution.
Impact on Outlook Users: The fix is particularly important for Outlook users who store PST files on OneDrive. Previously, certain Outlook configurations could hang or repeatedly reload email data when PSTs were stored on OneDrive. This build resolves those issues, ensuring smooth operation regardless of PST file location.
Understanding the Dev Channel Experience
What is the Dev Channel?
The Dev Channel is Microsoft's testing ground for features that will eventually make their way to the general Windows 11 release. While more stable than the Canary Channel, Dev Channel builds still represent pre-release software with potential issues.
Controlled Feature Rollout
Microsoft uses Controlled Feature Rollout technology to gradually introduce new features to Dev Channel users. This methodology:
- Starts with a subset of Insiders
- Monitors feedback and telemetry data
- Gradually expands the rollout as confidence grows
- Allows Microsoft to catch issues before they affect all users
Toggle for Early Access
Insiders who want to be first in line for new features can turn ON the toggle to get the latest updates as they become available via Settings > Windows Update. This option provides even earlier access to experimental features while they're being gradually rolled out.
Users who prefer a slightly more cautious approach can keep the toggle off, and new features will be gradually rolled out to their PC over time once they've been validated with early adopters.
Why These Updates Matter
For Security Professionals
The inclusion of built-in Sysmon is a significant win for enterprise security teams. Sysmon has become an essential tool for threat detection and incident response, and native integration simplifies deployment and management across large organizations.
Security teams can now:
- Deploy consistent monitoring across all Windows 11 devices
- Reduce external dependencies for critical security tooling
- Streamline security stack management
- Improve threat detection capabilities with minimal overhead
For General Users
The cloud storage fixes address real productivity pain points. As more users adopt cloud-first workflows, seamless integration between Windows and cloud storage providers becomes increasingly important.
Users can now:
- Work confidently with OneDrive and Dropbox without fear of application freezes
- Store Outlook PST files on OneDrive without performance degradation
- Enjoy improved File Explorer accessibility and functionality
For International Users
Expanded Voice Access support demonstrates Microsoft's commitment to accessibility across languages and regions. Each new locale addition makes Windows more inclusive and useful for diverse user populations.
Technical Details and Considerations
Build Information
Build 26300.7733 is based on Windows 11, version 25H2, delivered via an enablement package. This approach allows Microsoft to introduce new features and improvements without requiring a full operating system reinstall.
Desktop Watermark
As with all Windows Insider pre-release builds, the desktop watermark at the lower right corner is normal and expected. This visual indicator reminds users they're running pre-release software.
Localization Status
Some features in active development may not be fully localized immediately. Localization happens over time as features are finalized. Insiders who notice localization issues in their language are encouraged to report them via Feedback Hub.
Looking Ahead

Best Practices for Dev Channel Insiders
If you're running Dev Channel builds, consider these recommendations:
Use Appropriate Hardware
Don't install Dev Channel builds on critical production machines. Use secondary devices or virtual machines for testing.
Provide Feedback
Your feedback directly influences Windows development. Use Feedback Hub to report issues, suggest improvements, and share your experience with new features.
Stay Informed
Read release notes carefully to understand what's changing and what known issues exist. Check Flight Hub regularly to track which builds are in which channels.
Backup Regularly
Even though Dev Channel builds are generally stable, they're still pre-release software. Maintain regular backups of important data.
