Performance Optimizer: A patent for day 1 performance
CCleaner 6.0 Professional comes with Performance Optimizer, which includes patented technology that stops programs the user isn’t working with, draining a PC’s resources. It makes old PCs feel new again and new PCs stay fast, no matter how many programs are installed.
PCs use apps to run start-up items, background processes, and services invisibly in the background while not in use, which slows down the performance and running of machines. Performance Optimizer intelligently puts these apps ‘to sleep’ in order to redistribute resources to the task at hand, and then wakes them up instantly as soon as they’re needed.
50 new programs added to Software Updater
CCleaner Professional’s updated Software Updater ensures users get the latest version of the programs they use by applying new updates and patches which can help fix bugs and security vulnerabilities provided by the app or device provider. Improved Software Updater now supports an additional 50 applications (soon to increase to 200), including KMplayer, WinZip, Box Drive, Foxit Reader, Adobe Reader, and Nitro Pro. It will soon work with 200 additional apps, as further updates are provided throughout the year.
Update for free users
CCleaner 6.0 Free includes even more powerful cleaning definitions for Windows, Google programs, Apple programs, and the gaming platform Steam, which allows the user to free up space, and help make PCs run more smoothly.
