Windows System Components

Published by Microsoft

Core Windows system DLLs that are part of the operating system. These files should not normally be replaced manually.

Why You Need This

System DLLs like kernel32.dll, ntdll.dll, and user32.dll are core Windows components. If these are missing or corrupted, you should run Windows System File Checker (sfc /scannow) or repair your Windows installation rather than downloading individual files.
