. Windows will attempt to find and replace any corrupted system files automatically. Reinstall the Application:
Windows uses "API Sets" to organize its core functions. These are virtualized DLLs that redirect calls to the actual library responsible for a task. The api-ms-win-core-windowserrorreporting-l1-1-1.dll file specifically handles how applications communicate crashes or hangs to Microsoft. This allows the operating system to collect diagnostic data to improve future updates. It is typically part of the Universal C Runtime (CRT) and is found in the C:\Windows\System32 and C:\Windows\SysWOW64 folders. Common Causes for Errors
This file is a "stub" or "API set" DLL utilized by the universal Windows application architecture. Microsoft uses these API sets to route application commands to the proper system files.
The linker resolves to api-ms-win-core-windowserrorreporting-l1-1-1.dll automatically. Repairing these files will deploy missing DLL components:
The System File Checker is a built-in Windows tool that scans for and repairs missing or corrupted system files.
Run DISM /Online /Cleanup-Image /RestoreHealth to repair the Windows image component store.
