Windows 11 adds built‑in Sysmon for native threat monitoring in Insider builds
Microsoft is rolling native Sysmon monitoring into Windows 11 for devices in the Windows Insider program, enabling Windows Event Log-based threat detection with Sysmon’s event logging. The feature is disabled by default and must be explicitly turned on (after removing any manually installed Sysmon). Activation can be done via Settings > System > Optional features > More Windows features > Sysmon or via PowerShell/DISM, and it is rolling out to Beta/Dev Preview builds 26220.7752 and 26300.7733.
