Windows 11 builds 26300.7733 (Dev) and 26220.7752 (Beta) arrive with built-in Sysmon

Windows 11 Insider builds 26300.7733 for the Dev channel and 26220.7752 for the Beta channel are now available for download with a new system tool.

Windows 11 Dev Channel update

Microsoft released two new builds for Windows Insiders in the Dev and Beta channels. The builds are numbered 26300.7733 (Dev Channel) and 26220.7752 (Beta Channel) and are now available for download. Both builds are identical, bringing a built-in Sysmon functionality, expanded Voice Access availability, and fixes for several known issues.

Here's what's new in both builds:

[Built-in Sysmon]

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.
  • Go to Settings > System > Optional features > More Windows features > checking Sysmon or in PowerShell: Enable-WindowsOptionalFeature -Online -FeatureName Sysmon
  • To complete the installation, from PowerShell or command prompt run: sysmon -i

[Voice Access]

  • Support for the Netherlands locale has been added.

Here's what's fixed:

[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.

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