When should a full Windows reinstallation be considered as a last resort for persistent error 1058?

A full Windows reinstallation (clean install) should only be considered as a last resort if all other troubleshooting methods—including checking services, running SFC and DISM, resetting Windows Update components, addressing permissions, performing a clean boot, and even an in-place upgrade—have failed to resolve the persistent error 1058. This indicates a severe, unrepairable corruption of the operating system. Before proceeding, always ensure you have thoroughly backed up all important data, as a clean install will erase everything on the system drive.
