is a background process typically associated with Microsoft OneDrive or Microsoft Office on macOS. It is responsible for checking for and installing updates independently of the main application.
Traditional update mechanisms often rely on network connectivity, which can be a challenge for standalone systems. These systems may not have access to the internet or may require strict security controls, making it difficult to apply updates. The SUD was developed to overcome these limitations, providing a self-contained update solution that can operate independently.

Using Sysinternals Process Monitor, we observed the daemon over a 72-hour period.
The term "Daemon" (Unix/Linux for background service) combined with "Standalone" suggests a cross-platform origin. It is almost exclusively found packaged inside third-party installers using InstallShield or FlexNet Publisher . These systems may not have access to the
The Standalone Updater Daemon (SUD) is a system component designed to manage and facilitate software updates on a standalone system. This paper provides an in-depth examination of the SUD, its architecture, functionality, and benefits. We explore the motivations behind the development of SUD, its design considerations, and the challenges it addresses.
