RegCool 2.035 is a feature-rich, lightweight, and portable registry editor for Windows that serves as a powerful alternative to the built-in Registry Editor (regedit.exe). Developed by ntwind, the creator of popular tools like Classic Shell and StartIsBack, RegCool enhances the registry editing experience with tabs, real-time search, favorites, syntax highlighting, and advanced navigation tools — making it ideal for system tweakers, IT administrators, and developers.
