When users suspect that system files might be corrupted or missing, they can use the SFC command to check and restore the integrity of these critical files. It compares system files with those in the Windows installation source, ensuring that all system files are up-to-date and unaltered. 2. DISM (Deployment Imaging Servicing and Management) is a tool used for preparing, configuring, and servicing Windows images. It can service Windows images both online and offline, including the Windows operating system and the Windows Preinstallation Environment (WinPE). DISM can update the component store in system images, fix system image issues, and prepare devices for Windows To Go, among other tasks. Both tools are invaluable for maintaining and troubleshooting Windows systems.
