Registry problems are the common cause of Windows crashes, error messages, and degraded performance! RegDoctor can safely and quickly clean and repair Windows registry problems with a few simple mouse clicks! RegDoctor uses an intelligent, high-performance detection engine to accurately identify missing and invalid references in your Windows registry. Identified registry problems are listed and rated by risk level using an easy to understand color-coded system for your information.
