Temporary files and selected browser data can be cleared with a cleanup run, and the portable package comes as a ZIP file without an installer. CCleaner Portable also includes a Registry Cleaner for finding entries it identifies as issues.
What can it clean?
Custom Clean lets you choose categories of data to remove. These include Windows temporary files and browser items such as cached files, history, and cookies. Clearing cookies may sign you out of websites or remove saved site preferences, so select that category only when you want those records removed.
Cleanup and Registry tools
The Registry Cleaner scans for entries it flags as issues and offers fixes. CCleaner can save a backup of registry changes before applying them. That backup matters if a change causes a problem, since registry entries can be used by installed software.
- Choose cleanup categories in Custom Clean.
- Run the Registry Cleaner separately from file cleanup.
- Save the offered backup before applying registry fixes.
Working from the portable ZIP
The portable build is supplied as a ZIP package, so it does not use a conventional installation process. Extract the package and launch CCleaner when maintenance is needed. The selected cleanup runs on the Windows computer where the program is opened; the ZIP format makes it practical to keep the utility on removable storage.
