What Is CCleaner Professional?

CCleaner Professional is the premium version of CCleaner, developed by Piriform — a trusted UK-based software company now part of Avast. Unlike the free version, CCleaner Professional unlocks advanced features including real-time monitoring, automatic cleaning, scheduled cleaning, priority customer support, and software updater tools — giving you complete control over your PC’s performance and privacy on a continuous, automated basis.

Version after version, CCleaner Professional has maintained its reputation as the fastest, most reliable, and most effective PC cleaner on the market. It removes junk files, clears browser history and cookies, fixes registry errors, manages startup programs, updates outdated software, and monitors your system in real time — all from one clean and intuitive dashboard.

Key Features

PC Cleaner — Remove Junk Files Instantly Over time, your Windows PC accumulates thousands of unnecessary temporary files, cache files, log files, error reports, and leftover installation files that slow down your system and waste valuable storage space. CCleaner Professional scans and removes all of this digital clutter in seconds — freeing up gigabytes of disk space and significantly improving system speed and responsiveness.

Browser Privacy Cleaner CCleaner Professional cleans your browsing history, cookies, cached web pages, download history, saved passwords, and autofill data from all major browsers including Google Chrome, Mozilla Firefox, Microsoft Edge, Opera, and Internet Explorer. Protect your personal information and browsing habits from being tracked or exposed — with one click or automatically on a schedule.

Registry Cleaner and Repair The Windows registry accumulates broken, outdated, and corrupted entries over time — causing errors, crashes, and slowdowns. CCleaner Professional’s powerful registry cleaner safely identifies and removes invalid registry entries, fixing errors and improving system stability without risk of data loss.

Startup Manager — Speed Up Boot Time Too many programs launching at startup is one of the most common reasons Windows PCs become slow to boot. CCleaner Professional’s startup manager gives you full control over which applications launch when Windows starts — letting you disable unnecessary programs and dramatically reduce boot times so you get to work faster every day.

Real-Time Monitoring CCleaner Professional’s real-time monitoring feature runs quietly in the background, watching your PC for junk files and performance issues as they happen. You receive instant notifications when it’s time to clean, and you can set it to clean automatically — so your PC is always performing at its best without any effort on your part.

Automatic and Scheduled Cleaning Set CCleaner Professional to clean your PC automatically on a schedule that suits you — daily, weekly, or monthly. Automatic cleaning ensures junk files never build up, your browser stays private, and your system stays fast — completely hands-free. This feature is exclusive to CCleaner Professional and is not available in the free version.

Software Updater Outdated software is one of the biggest security risks on any Windows PC. CCleaner Professional’s Software Updater tool scans all installed applications and identifies outdated versions that need updating. Update multiple programs at once with a single click — keeping your software current, secure, and compatible with the latest standards.

Driver Updater Outdated device drivers can cause hardware conflicts, crashes, and poor performance. CCleaner Professional includes a driver updater that identifies outdated drivers for your hardware components and helps you update them safely — ensuring your PC runs smoothly and all devices function correctly.

Uninstaller — Remove Unwanted Programs Completely Standard Windows uninstallation often leaves behind leftover files, folders, and registry entries. CCleaner Professional’s advanced uninstaller removes programs completely — including all associated files and registry entries — so nothing is left behind to slow down your system.

Duplicate File Finder Duplicate files waste significant amounts of storage space without you realizing it. CCleaner Professional’s duplicate file finder scans your entire PC and identifies identical files so you can safely delete duplicates and recover valuable disk space quickly and easily.

Health Check — One-Click PC Optimization Not sure where to start? The Health Check feature scans your entire PC and gives you a complete overview of issues affecting your system’s speed, privacy, and security — then fixes everything automatically with a single click. Perfect for users who want fast results without technical knowledge.

File Shredder — Permanent and Secure File Deletion When you delete sensitive files, they can often be recovered using file recovery software — posing a serious privacy risk. CCleaner Professional’s file shredder permanently and securely deletes files using military-grade overwriting techniques, making them completely unrecoverable. Ideal for deleting confidential documents, financial records, and personal files safely.

Free Disk Space Wiper Even deleted files can leave recoverable traces on your hard drive. CCleaner Professional’s free disk space wiper overwrites all free space on your drive, ensuring that previously deleted files cannot be recovered by anyone — providing an extra layer of privacy and security for your data.

Priority Customer Support As a CCleaner Professional license holder, you receive priority access to Piriform’s dedicated customer support team. Get faster responses, expert assistance, and professional guidance whenever you need help — ensuring you get the most out of your software throughout your entire 1-year license period.
