This is a Core Windows System File

usosvc.dll is a critical Windows component. If it's missing or corrupted, you should repair Windows rather than replace the file manually.

Recommended: Run System File Checker

Why You Shouldn't Just Download the DLL

  • DLLs depend on other DLLs - copying one file won't fix the chain
  • Runtime packages register components in Windows correctly
  • Version mismatches can cause more problems
  • The official installer handles all of this automatically
