Verified with Windows 11 25H2 — updated on July 30, 2026
Supported on: At least Windows Vista
Path in the GPO console
Computer Configuration\Administrative Templates\Windows Components\Event Log Service\Setup Description
This policy setting specifies the security descriptor to use for the log using the Security Descriptor Definition Language (SDDL) string. You must set both "configure log access" policy settings for this log in order to affect the both modern and legacy tools. If you enable this policy setting, only those users matching the security descriptor can access the log. If you disable this policy setting, all authenticated users and system services can write, read, or clear this log. If you do not configure this policy setting, the previous policy setting configuration remains in effect.
