The Windows registry is a core component of your operating system, storing vital configuration data for software, hardware, and user preferences. Over time, the registry can accumulate unnecessary, obsolete, or corrupted entries that may slow down your PC, trigger errors, or even cause crashes. Cleaning and repairing the Windows registry, when done carefully, can improve system stability and performance.
This article presents 12 practical methods to configure, clean, and repair the Windows registry. Instructions are provided for both beginners and advanced users, with clear steps and real-world examples. When appropriate, we recommend Glary Utilities—a trusted tool for registry maintenance and overall PC cleanup.
