• IE, Firefox, Google Chrome, Opera, Safari - temporary files
• Windows - Recycle Bin, recent documents
• Registry Cleaner - advanced cleaner removes unused and old entries
• Third Party Tools - removes temporary files and recent file lists (MRUs) from many applications

List of new and improved cleaning definitions in Windows 11

CCleaner has added a list of Windows 11 features and applications that it cleans. These include:

• Windows 11 widgets: these widgets display weather information or news feeds. However, they generate cached items such as logs, temporary JavaScript files, and images in more than a dozen places on the device. CCleaner can now automatically delete these files.

• Microsoft Teams: the "Teams" collaboration, video conferencing and chat tool is now fully integrated into Windows 11. Teams generates a large amount of cached data, logs and other temporary files (13 types in total), which CCleaner now cleans.

• Skype: Windows 11 includes the communication app Skype, which CCleaner cleans by removing cached data.

• Microsoft Messages: The new Messages app in Windows 11 generates cached data, including temporary Internet files (images, HTML data) and cookies, which CCleaner can remove.

• Windows Defender: The integrated Windows Defender tool generates a number of logs that don't need to be stored long-term. CCleaner detects and removes these files.

• OneDrive: CCleaner also cleans new cached files from OneDrive in Windows 11.

• File Explorer (formerly Windows Explorer). CCleaner can now detect and remove old search data, logs, and shortcuts for recently used files.

• Microsoft Family Security: CCleaner cleans up temporary files and folders from Family Security.
