CCleaner®6 delivers up to 34% more speed + 30% more battery life with Performance Optimizer

New feature uses proven technology built to deliver performance

New in CCleaner 6, Performance Optimizer scans for applications running in the background and disables them safely, improving your PC's performance by reserving your computing resources for the apps you want to use.

Performance Optimizer is brand new, patented technology. Because it’s a world-first, we ran a series of benchmark tests to help you understand how well it improves startup time, work performance, gaming, battery life, and even power consumption on both old and brand new PCs.
