On most counts, this Registry cleaner strikes us as a positive affair. The program's interface is professional-looking, colorful, and logically arranged, with prominent buttons for scanning your computer for errors and compacting the Registry. By default, the program is set to scour the entire Registry, but if you like you can add or remove items such as fonts, invalid shortcuts, file extensions, and shared DLLs. The program can automatically back up the Registry before a scan, but this feature only seems available to XP users. It's nice that RegRestore PC TuneUp tells you the location of problematic keys and tells you how serious they are. Still, we'd like to see a scheduling utility, a perk available in many programs in this class. Scan times weren't unreasonable, but since the demo only will remove entries from half of the categories, you may need to get your hands dirty manually or find another program if you expect a pristine Registry. But in the final analysis, RegRestore PC TuneUp has some good things going for it.
