Key Features of CCleaner Key 2025

Faster Computer

As systems age, they accumulate temporary files, unused data, background tasks, and outdated drivers that slow down performance. CCleaner speeds up your PC by cleaning junk, pausing unused apps, and updating drivers, all of which contribute to a faster and more responsive system.

Browser Cleaning

Modern browsers leave behind cookies, caches, trackers, and temporary data that clutter disk space and affect browsing speed. CCleaner clears this browsing residue from all major browsers, resulting in improved performance, smoother loading times, and enhanced privacy.

Registry Cleaner

Over time, the Windows registry becomes cluttered with invalid entries and leftover configurations, leading to errors and instability. CCleaner’s registry cleaner removes these unwanted entries safely, helping to reduce crashes, fix errors, and improve system stability.

Quicker Startup

Many programs run silently during startup, slowing down your system’s boot process. CCleaner allows you to manage and disable unnecessary startup apps, ensuring a quicker startup and faster access to your desktop every time you turn on your PC.
