Main features of Ashampoo WinOptimizer 16:

Design is combined with performance
WinOptimizer 16 not only looks amazing, but it has never been so smart. The program notifies you of potential system problems and provides a solution right at the start. The new design is extremely intuitive, and the controls are super intuitive. You will see excellent results in just a few clicks. The redrawn interface is thought out to the smallest detail!
Boundless power
Our most popular modules have been completely revised and updated for the best speed and stability. As a result, classic modules like Duplicate Finder and Undeleter are now up to 50 times faster! Even DiskSpace Explorer, which usually processes huge amounts of data, is now up to 10 times faster. Phenomenal acceleration was obtained in WinOptimizer 16 thanks to low-level system programming by our system tuning specialists!
More security, security and disk space
Powerful WinOptimizer 16 cleaning tools will rid your system of garbage. And these are not only temporary or cached files, but also unnecessary cookies and your browser history, which can damage your privacy. In addition, you can search for duplicate files, such as copies of photos or documents that you may have saved in several places.
Classic: one-click optimization
One-click optimization fixes multiple problems at a time with 3 powerful modules. Internet Cleaner removes browser traces, which not only frees up space, but also increases your privacy. Drive Cleaner removes unnecessary more files, freeing up disk space. Registry Cleaner removes incorrect registry entries, preventing system crashes and speeding it up. Magic with just one click.
Privacy control specifically for Windows 10
Windows 10 collects more user data than any Windows before. The Win10 Privacy module gives you back control on your PC! Finally, you decide which passwords and telemetry data or photos are sent to Microsoft. Or you can keep everything to yourself! Allow the app to update automatically or even allow them access to your messages or calendar? The choice is yours, and Ashampoo WinOptimizer 16 will strictly follow up for you!
Full on-demand performance
Need all the power of your PC? Live-Tuner and Game-Booster are rushing to the rescue! Live-Tuner changes priorities and speeds up applications when needed. Game-Booster completes non-critical background processes and applications to provide you with maximum resources and optimal performance in games. After exiting the game, the system will be returned to its previous state - brilliant!
Advanced cleaning tools
For maximum accuracy, cleaning products are constantly updated. Browser traces and temporary files are hidden in various places on your hard drives. Ashampoo WinOptimizer 16 constantly searches for such files and provides in-depth removal on demand.
Automatic cleaning instantly!
WinOptimizer uses smart algorithms to automatically delete unnecessary files. Browser traces and temporary files will be deleted immediately after you close the browser. Nothing will hide from automatic cleaning, including Adobe Flash, Reader, Quicktime and temporary Java files! Your files will always be safe, and the system is fresh and fast!
Don't let your system out of sight
Ashampoo WinOptimizer 16 will show you what is happening on your machine. For example, if the condition of your hard drives has deteriorated, you will instantly know about it before trouble occurs.
