Frequently Asked Questions

Is this different from a normal "file corrupted" error?
It's more specific — this points to a component in the Windows servicing store (the system that tracks what's installed) being damaged, which is exactly what DISM /RestoreHealth is designed to repair.
Do I need internet access for the DISM fix to work?
By default, yes — DISM pulls replacement files from Windows Update. Without internet access, you'd need to specify a Windows installation source manually instead.
