BleachBit at a glance
Checked 21 Oct 2026BleachBit (6.0.6 for Windows 10 and 11, actively developed since 2008) cleans temporary files, logs, browser caches, history and cookies, with a preview of every file before deletion. It shreds files, wipes free space, has a command line for scripting and imports thousands of extra Windows cleaners from winapp2.ini. GPL-3.0 or later, no account, no paid tier. It does not update drivers or apps, manage startup programs or clean on a schedule by itself.
