Registry TuneUp is one of the most advanced and effective best registry cleaners you will ever find. It is a tool to optimize clean and tune up your system registry - the most important part of windows. It finds and removes errors in your windows system registry, reducing application crashes, and thus enhancing the performance and reducing sluggishness. It cleans all parts, yet it is the safest, using a built-in ignore list to prevent important entries in the registry from being listed. It allows 'undo' operations, has normal and expert modes, and is very fast and powerful.
Registry TuneUp is an application made from the 'Clean System Registry' tool of Ace Utilities and offered at a lower price. If you want a complete system maintenance utility, we recommend Ace Utilities. All the features of Registry Tuneup are contained in Ace Utilities.
