CCleaner's free edition gains Active System Monitoring

Piriform Ltd has released CCleaner 4.18 and CCleaner Portable 4.18, the latest versions of its popular Windows cleanup tool.

This time the big addition is a limited version of Active System Monitoring, a smart feature previously reserved for the commercial CCleaner Professional. Turn it on and CCleaner monitors your system, checking for junk, and lets you know when it’s time to clean up.

What you don’t get is browser monitoring, or any control over what CCleaner does when triggered (it just displays a message): those features are still Professional-only. Click the new Monitoring button to get a feel for what you’re missing.

Elsewhere, there’s new support for cleaning Ashampoo Burning Studio 14, XnView and FastStone Capture.

Piriform reports improved cleaning of Opera History and Firefox Saved Passwords.

There are also improvements to the 64-bit build for Windows 8/ 8.1, localization tweaks, and the standard scattering of minor interface adjustments and bug fixes.

Launch CCleaner and it’ll probably point you to the new build all on its own (see Options > Settings > "Automatically check for updates…", if not). Otherwise downloads of CCleaner 4.18 and CCleaner Portable 4.18 are available now.
