This is where the Deployment Imaging Servicing and Management (DISM) tool becomes vital. DISM is a more advanced utility designed to service the operating system image itself. By running commands such as DISM /Online /Cleanup-Image /RestoreHealth , users can instruct Windows to download fresh, uncorrupted files directly from Windows Update servers to repair the local Component Store.
