As he continued to investigate, John discovered that the api-ms-win-core-windowserrorreporting-l1-1-1.dll file was a legitimate Windows DLL, responsible for error reporting and Windows Core functionality. It seemed that the file had gone missing or was corrupted during a recent Windows update.
Because this is a "Core" component, its absence implies a problem with the foundational Windows system files or the Universal C Runtime (CRT).
Modern Windows operating systems separate application-level requests from core kernel processes using specialized virtual DLL files known as API Sets.
