CCleaner is a PC cleaning tool that removes unnecessary files, frees up disk space, and improves your system performance.
CCleaner, compatible with Windows, MacOS, and Android, is a system optimization and cleaning tool with several features and modules. Its main objective is to speed up the operating system by erasing unnecessary files and traces of internet usage and browsing. Computer optimization is achieved by clearing obsolete files and unnecessary keys in the system registry.
In addition to uninstalling unnecessary software, CCleaner offers the option to disable unnecessary services or programs during device startup, thereby contributing to better performance and security for users. The license price varies depending on the features and options available.
The cleaner
The main CCleaner module, in addition to freeing up disk space, plays a crucial role in protecting user privacy and security. The software is capable of detecting and clearing temporary data, cookies, and browsing history from major internet browsers, including Edge, Internet Explorer, Google Chrome, Mozilla Firefox, and Brave. CCleaner extends its cleaning experience to third-party applications, including Windows Media Player, Microsoft Office, WinRAR, Nero, and Adobe Acrobat Reader DC, thereby optimizing disk space and computer performance.
CCleaner also performs a deep scan of Windows system items, including Recycle Bin, recent files list, system logs, cache, etc. It comes in multiple versions, including a free version and a portable version, making it suitable for different types of users.
The registry tool
CCleaner offers an essential feature for the optimization and performance of your computer or device: cleaning the Windows Registry. The latter, a crucial part of the operating system, can often become cluttered with redundant or invalid entries, which can affect the performance and security of your system. With CCleaner, you can easily launch a deep scan of the Windows Registry with a single click, an option that improves user experience.
Once the scan is complete, the software provides you with a detailed report of detected issues, including obsolete files and keys. You then have the option to fix all of these issues at once or address them individually, giving you complete control over the use and optimization of your system.
Program management
CCleaner integrates various software and application management tools, including an advanced uninstaller, a software update utility, and a browser plugin manager. Unlike standard Windows system tools, the advantage of CCleaner is its ability to also reference pre-installed Windows applications, which are often omitted by the Control Panel. These are native applications like Cortana, Tips, Movies and TV, Messages, or even Microsoft Solitaire Collection, which can take up disk space without actually being used. This feature is also applicable to software pre-installed by the computer manufacturer.
The integrated tool kit
CCleaner doesn’t stop there and provides several additional features via the Tools tab:
-
- Uninstallation of programs: software uninstallation interface useful for renaming or deleting an entry;
- Startup: three tabs allowing you to activate, deactivate, or clear entries concerning the execution of applications at Windows startup, scheduled tasks as well as the Windows context menu accessible via a right click;
- Browser plugins to enable or disable Internet Explorer, Mozilla Firefox, Google Chrome, and Opera web browser extensions;
- Disk Scan to analyze hard drives to learn about the largest files;
- Duplicate File Finder allows you to detect and remove duplicate files;
- System Restore to remove unnecessary restore points and therefore save storage space;
- Disk eraser is a module for performing secure formatting of disks or storage devices using several methods.
