What Are Registry Errors?

The Windows registry is a database that stores settings for your operating system and programs. When software is uninstalled incorrectly or malware infects your PC, corrupt or invalid registry entries can pile up, leading to:

Slow startup and shutdown
Frequent crashes
Unexpected error messages
Unresponsive applications
