CCleaner Professional 7

The world's most recognizable optimization tool. In late 2025, CCleaner 7 introduces Cloud Drive Cleaner (OneDrive/Google Drive), automated performance scheduling, and a revamped Driver Updater supporting over 5 million devices. While its 'Health Check' remains the gold standard for beginners, its legacy of security breaches and its persistent 'Premium' upsells in the free version continue to drive power users toward open-source tools.
