Limit privileges of user accounts and groups so that only authorized administrators can interact with service changes and service binary target path locations. Toolkits like the PowerSploit framework contain PowerUp modules that can be used to explore systems for service file system permissions weaknesses.

Consider enabling installer detection for all users by adding: \"EnableInstallerDetection\"=dword:00000001. This will prompt for a password for installation and also log the attempt. To disable installer detection, instead add: \"EnableInstallerDetection\"=dword:00000000.
