Over time, operating systems tend to slow down, become unstable and clutter up. Important settings are also either missing or hidden deep within the system. WinOptimizer whips your PC back into shape and makes it feel like new again. Let WinOptimizer clean, optimize and protect your machine and enjoy a fast, lean and secure Windows PC with intact privacy, permanently!

Privacy Traces Cleaner tracks down, and eliminates, sensitive data that may compromise your privacy and security. A new tuning assistant helps you to individually optimize your system by answering a few questions. One Click Optimizer now runs four cleaners, and UnInstall Manager 2.0 handles regular software as masterfully as Windows apps. System Analysis provides more detailed information, and the new Windows Notification Center integration ensures you won't miss a thing even when the program is minimized!


More tuning through dialog

Windows auto-optimization has been an integral part of WinOptimizer for the longest time. Time to take care of the rest! The Tuning Assistant will ask you few simple questions with far-reaching consequences. Each response will bring you closer to a faster, more discreet, and more secure Windows machine–all while having a casual conversation with our software. Disable unnecessary background services, optimize security settings, and customize Windows for better performance and privacy, risk-free!


With the new and extended in-depth cleaning, the hunt for junk files enters a new phase–and privacy and display issues are also easily fixable now! Get rid of old Windows versions, Windows update backups, and Windows usage statistics. Fix display issues in your games by emptying the DirectX shader cache, and speed up your slow Windows Explorer by clearing the preview cache. You'll also regain loads of hard disk space in the process.

Four-way cleaning of unnecessary files

Our popular cleaners now includes Privacy Traces Cleaner for four-way cleaning action! Junk files, web browsing traces, invalid Registry items, and privacy-sensitive data are now on the chopping block! Whether Drive Cleaner or Internet Cleaner, results appear almost instantaneously and detection rates are off the charts, while custom file filters help you to adjust and extend the range of supported file types. Our cleaners are meticulously tailored to all modern Windows versions and browsers.


All applications leave behind traces that may compromise your privacy (and security). Privacy Traces Cleaner features specially designed search algorithms that scan files, folders, and the Windows Registry for such traces, and eliminate them after your review and confirmation. There's a built-in Registry backup feature for added safety, whitelisting for individual exceptions, and multi-user support so you can clean all user profiles at one time.

Take control of your online privacy

Despite their usefulness and added comfort, internet cookies have become something of a privacy nightmare recently. The innovative cookie manager will help you safely manage your cookies across all of your browsers! Preserve login sessions while eliminating cookies that invade your privacy. Use wildcard characters to instantly mark entire domains as safe–your settings will apply to all of your browsers and can be exported and imported for easy transfer across devices.


Ashampoo WinOptimizer 26 makes full use of the system-wide Windows Notification Center to provide you with valuable updates. You will be notified when time-consuming analyses are complete, even when the program is minimized. Let One Click Optimizer, File Wiper, Disk Doctor and others do their jobs in the background while you're doing something else. You'll be notified as soon as they're done, no more need to watch the progress bars.
