CCleaner 5.12.5431 Free, Professional, Business and Technical Edition


If you have CCleaner already installed on your PC, than let the program automatically update and download only the key to register. Other wise you must download the installer and the key.

Your computer is not only at risk from being infected by malicious software, residues left after uninstalling applications and so-called junk files can significantly reduce oerformance. However perodic scans and cleaning can keep your PC in good shape. One of the applications that can aid in this situation is CCleaner, equipped with all tools needed to scrub every bit of your computer.

We've also optimized internal architecture so CCleaner will launch quicker than ever before.
