ERROR_REGISTRY_HIVE_RECOVERED
Windows recovered a registry hive after detecting corruption
Registry hives have supporting files used to maintain persistent state and recover consistency. This status is not the same as ERROR_REGISTRY_CORRUPT: Windows reports that recovery succeeded far enough to make the hive usable, but the system explicitly warns that some data may have been lost.
Treat the event as a recovery result that still requires root-cause analysis. Record the hive path, preserve the recovered hive and its supporting files, and correlate the time of recovery with storage, power-loss, crash, or disk events. Application failures after recovery may come from missing recent values rather than ongoing structural corruption. Compare important service, driver, policy, or application configuration with a known-good export or backup. Rewriting many values immediately can obscure which settings were actually lost.
What to inspect
- Identify the recovered hive and save a copy before further writes.
- Correlate recovery with disk, reset, crash, or unexpected-power events.
- Compare critical configuration against a known-good backup or exported baseline.
