Damaged files or incorrect registry entries resulting in the 0x80070005 error can arise due to very different circumstances. For example, improperly starting up or shutting down the PC (e.g. after a blue screen) can be the cause, as can defective hardware (particularly the hard disk), or even malware. In addition, it is always possible that the user is responsible for the incorrect settings because they – consciously or unconsciously – have made changes to the registry or deleted files. In many cases, so-called registry cleaners or similar performance optimization tools can be effective. These tools are designed assist the user in clearing up and repairing the registry database, but sometimes go beyond their actual purpose.
