Description: The ‘RunOnce’ key in the Windows Registry is a tool that allows a specific program to run automatically only once at the next system startup. This functionality is particularly useful for applications that require initial setup or need to perform maintenance tasks that do not need to be repeated at every boot. By storing the program’s path in this key, Windows ensures that the application starts once and then removes it from the list, thus preventing repeated execution on future boots. This feature is part of operating system startup management systems, allowing users and administrators to control which applications run at system startup, thereby optimizing performance and user experience. The ‘RunOnce’ key is located in a specific area within the Registry, enabling advanced users and system administrators to effectively customize their operating systems’ startup behavior. Its use is common in environments where initial software configuration is required or in situations where scripts or installation programs need to be executed that should not be repeated at each startup.
