Overview

What this release is

CCleaner is the maintenance utility that has been on more machines than almost any other tool in this category, and the reason is that it does the boring housekeeping quickly and without drama. Temporary files, cache folders, browser history, and the sediment that builds up behind normal use are found and cleared in one pass, which reclaims space and tidies the traces of a browsing session in the same run.

The registry cleaner is the part longtime users reach for after uninstalling software. It finds the orphaned entries that an uninstaller leaves behind, offers to back up the registry before it changes anything, and works through the list conservatively rather than aggressively, which is the right temperament for a tool touching the registry at all.

Beyond cleaning, it manages the things that slow a machine over time. Startup programs can be disabled, browser plugins reviewed, duplicate files found, and large disk hogs located, all from one interface rather than four separate Windows dialogues buried in different places.

The Professional configuration adds scheduled automatic cleaning, real time monitoring, and the full driver and software update checks, and this build has that tier enabled from first launch without a trial timer.

Questions

Before you start

Is the registry cleaner safe to run?

It is conservative and backs up before changing anything. Keep the backup until you have confirmed the machine is fine.

Does it speed up a slow machine?

It reclaims space and trims startup programs, which helps. It is maintenance, not a hardware upgrade.

What does the Professional tier add?

Scheduled cleaning, real time monitoring, and the update checks, all enabled in this build.

Will it clear saved passwords?

Only if that option is selected. Review the cleaning selections before the first run to avoid clearing anything you want kept.
