Why BleachBit?
Completely free with no adware, spyware, telemetry, or bloatware. Includes a preview mode so you can see exactly what will be deleted before committing. Runs portably from a USB drive on Windows.
BleachBit outperforms CCleaner 7 by avoiding its notorious issues like a confusing redesigned UI, aggressive cleaning that breaks browser settings and programs, and forced telemetry with bloatware background processes. Instead, BleachBit delivers open-source transparency, precise granular controls, including winapp2.ini support, and lightning-fast cleaning without hidden data collection or upsell nagging. Power users love its reliability over CCleaner 7's crashes and restricted features.
