Explanation
SFC (System File Checker) is the correct tool. Running 'sfc /scannow' from an elevated command prompt scans all protected Windows system files - including DLLs - and replaces corrupted or missing ones from a cached copy in %WinDir%\System32\dllcache. This directly addresses missing DLL errors at startup. msconfig manages startup entries and boot configuration but cannot restore files. Computer Management is an administrative console with no file repair capability. regsvr32 registers or unregisters a specific DLL already present on disk but cannot retrieve missing ones.
