CCleaner Professional Original Annual License for Windows

Trusted Shops Guarantee, Fast Email Delivery and Technical Support Included

CCleaner Professional is the world's most widely used cleaning and optimisation program for Windows: it takes back the space Windows and browsers use up without saying so, and puts order among the programs that start by themselves when the computer is switched on. The Professional version adds real-time automatic cleaning and updates for installed programs. The license is annual and is delivered by email with the activation code.

Why choose CCleaner Professional

A Windows computer gradually accumulates temporary files never deleted, registry entries left after uninstalls and programs that start at power-on without being needed. Each weighs little, but together they lengthen boot times and reduce free space. CCleaner tackles all these fronts in a single operation.

The difference from the free version lies in automation: Professional works in the background and cleans when needed, instead of requiring the user to remember to run a scan now and then. It also adds automatic updating of installed programs, a useful function because outdated software is one of the most exploited entry points.

What CCleaner Professional is and what it is for

CCleaner Professional scans the system and identifies what can be safely removed: temporary files, browser caches, logs, thumbnails and registry entries that are no longer valid. Before acting it shows the list of what will be deleted and creates a restore point for the registry.

Alongside cleaning are the control tools, and that is the part you feel most on a computer a few years old: a laptop that takes two minutes to reach the desktop usually has a dozen programs switching themselves on, and none of them is needed before the first document is opened. All operations can be scheduled to run periodically, with no manual intervention.

What you really lose when you delete everything without looking

• Deleted cookies mean signing out of every site
  Next time round you sign back in everywhere, and if the password is not saved somewhere the hunt begins. It is worth excluding the sites you use every day.
• The browser cache is not rubbish
  It is why frequently visited sites open at once. Emptying it every day means redownloading the same images every day, and browsing more slowly.
• History is more useful than people think
  It is how you find again that page read on Tuesday whose name you cannot remember. Deleting it out of habit costs more than what it protects.
• Passwords saved in the browser can end up in the cleanup
  It is the option to look at twice before pressing. If there is no separate password manager, that tick deletes access to dozens of services.
• Temporary files are the only entry that is always safe
  Those come off without thinking: no program misses them. It is also the entry that frees the most space of all.
• An emptied bin is not a deleted file
  Until it is overwritten, a removed file is recovered with common tools. Whoever sells or gives away a computer has to know this.
• Programs that start at switch-on are turned off, not uninstalled
  Removing a program from the automatic start does not remove it: it leaves it available when needed. It is the difference between tidying up and doing damage.
• What should not be touched lightly
  Registry entries and program files you do not recognise. If a cleanup offers to remove something you do not know, the right answer is to leave it.
