What does Registry Defrag do?
The problem: Your PC may be having intermittent freezes, slow application response or other stability problems. Combined with high memory usage, these issues may significantly reduce your computer's performance.
The solution: Driver Updater will check your computer for potential driver problems, give you a report on outdated or missing drivers it detects, and let you quickly update them to the latest manufacturer-recommended versions.
