While the jury is still debating the efficacy of Registry cleaners, Registry Repair from Glary seems to do its main job quickly and accurately. True to its name, the utility scans your PC's Registry, then fixes any errors it finds. Some of the extras are worth noting, too.
The app's main interface is easy to grasp at first sight, letting you check and uncheck boxes when deciding which portions of the Registry to scan. For instance, the program looks for such entries as obsolete software, invalid fonts, bad shortcuts, and even spyware. It's also handy that Registry Repair offers a brief explanation of why each key is no longer necessary. Nevertheless, it takes no risks and automatically backs up the Registry before you remove anything.
In addition to its main job, the application also can manage which programs launch on start-up. You'll also find a disk-cleanup utility and an uninstaller. These features are not remarkably different from Windows' built-in tools, but it's still nice to be able to access them from the app's main window.
