DISM and SFC

The Component Store [%WinDir%\WinSxS] maintains a backup copy of all Windows system files, and SFC [System File Checker] & DISM [Deployment Image Servicing and Management] manage two separate, vital pieces of the Component Store and OS, with SFC relying entirely upon what DISM manages: DISM has two functions SFC relies upon, /StartComponentCleanup and /RestoreHealth, with /RestoreHealth relying Continue reading →
