CCleaner 4.00 adds two new features but limits one to Pro version

Piriform has released CCleaner 4.00 and CCleaner Portable 4.00, major new release of its popular free cleaning tool for Windows users. Version 4.0 includes two new tools, but for the first time restricts one of these to paid-for users with Pro licenses only.

Version 4.0 also debuts a new program icon and tweaked user interface, added support for cleaning additional programs and the usual raft of performance and stability tweaks, including unspecified improvements to the program’s internal architecture for better performance.

CCleaner 4.0 adds two new tools to its armory, only one of which is available to those running the free version. This is a Duplicate File Finder, accessible from the Tools section of the program. Users select what criteria to match by – including name, size and last modified date – what to ignore and which drives, folders and wildcards to both include and exclude from the search. Users then click the Search button to review and manually select which copy or copies of each duplicate file to delete.

The second new feature is a browser and system monitoring tool, but this is restricted to Pro users only.

The Registry Cleaning tool has been optimized and improved, while Drive Wiper should also now benefit from improved performance. The Startup item detection algorithm has been improved, as has the 64-bit CCleaner build for Windows 7 and 8.

Cleaning support has been extended to Samsung Kies along with the latest versions of Avast! Antivirus (v8), Adobe Photoshop (CS6) and Real Player (v16). The update is rounded off with the usual mix of unspecified performance improvements and bug fixes.

CCleaner 4.00.4064 and CCleaner Portable 4.00.4064 are both available as free-for-personal-use downloads for Windows PCs running XP or later.
