Prohibit non-administrators from applying vendor signed updates
Verified with Windows 11 25H2 — updated on July 30, 2026
Supported on: Windows Installer v3.0
Path in the GPO console
Computer Configuration\Administrative Templates\Windows Components\Windows Installer Description
This policy setting controls the ability of non-administrators to install updates that have been digitally signed by the application vendor. Non-administrator updates provide a mechanism for the author of an application to create digitally signed updates that can be applied by non-privileged users. If you enable this policy setting, only administrators or users with administrative privileges can apply updates to Windows Installer based applications. If you disable or do not configure this policy setting, users without administrative privileges can install non-administrator updates.
