They need to be re-installed after a clean Windows OS installation. SetupDiag is a Windows diagnostic tool that helps you determine the cause of a Windows installation failure. SCCM (System Center Configuration Manager) is an installation option that you can use if you are currently running Configuration Manger to manually deploy operating systems and managing software updates through the tool. You would not normally use Configuration Manager to upgrade Windows 4.2.12 Windows Upgrade Facts
