Ashampoo WinOptimizer 26 makes Windows PCs faster, cleaner and more discreet. The system analysis at launch time provides numerous options to optimize and clean your operating system right from the start page. The built-in cleaner modules have now become genuine classics and rid your machine of even more web browsing traces, temporary files and leftover files from software uninstallations.

The cleaners in version 26 are record-breaking both in speed and thoroughness. Auto-Clean, Live-Tuner and Game-Booster keep your system clean and ensure that programs launch faster and games run more smoothly. For a condensed but always up-to-date system overview, WinOptimizer comes with data-rich dashboards that also act as quick shortcuts to essential modules.

The tweaking module allows for individual Windows customization and features all the latest tweaks also for Windows 11. WinOptimizer 26 comes with Privacy Traces Cleaner to hunt down and eliminate privacy-related data, and a new question-based tuning assistant for custom system optimization.

The popular 1-Click Optimizer now bundles four modules for superior cleaning results and, as a first, the program now relies on Windows Notification Center for smooth and unobtrusive status updates.

Finally, performance and information presentation has been improved across all 30 WinOptimizer modules and new features have been added.

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 in one go.
