    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.

    Windows is great–but there's always room for improvement. That's where Ashampoo WinOptimizer 26 comes in! Because, over time, operating systems tend to slow down, become unstable and clutter up.

WinOptimizer 26 puts a stop to this, fast, easy and effectively! It 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!

The innovative cookie manager will help you safely manage your cookies across all of your browsers! Separate the wheat from the chaff and 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.

    First-rate but second-row features

    Over 30 Top-notch modules for every purpose - Beyond cleaners and optimization

    Aside from cleaners and optimizers, WinOptimizer also offers modules that other companies would rather sell you as separate applications. This includes Process Manager for a better look at what is running on your PC, and Privacy Manager for better privacy protection. These are joined by Icon Saver, to bring more order to your desktop, and File Wiper, to permanently erase sensitive data. In total, WinOptimizer features over thirty cutting-edge tools that cover the whole spectrum of system cleaning, tuning, and optimization!

    Next-gen privacy protection with Privacy Traces Cleaner

    Find and delete sensitive data

    Whether you use Windows apps, games, or office suites, 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, of course! 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.

    See what's happening on your machine

    Essential information neatly arranged right off the bat

    The newly designed system analysis tells you everything you need to know at a glance. Aside from the CPU load speedometer, you now also get a first-hand look at disk usage and privacy-related information, courtesy of our new Privacy Traces Cleaner! Increase the size of the program window for even more valuable system details, like number of irrelevant files, services, and Registry entries, or the amount of potentially reclaimable disk space. The system analysis will tell you what you need to know!

    More tuning through dialog

    Effortlessly optimize your windows with the Tuning Assistant - Unleash maximum performance and privacy!

    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!

    Windows Notification Center integration

    Native notifications with essential details even when the program is minimized

    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. Naturally, time and frequency of the notifications is fully customizable.

    New cleaners with more power and efficiency

    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 now 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. Naturally, our cleaners are meticulously tailored to all modern Windows versions and browsers.

    New features in manager modules

    Cleaner uninstalls and more information when it matters!

    UnInstall Manager 2 now also processes, and uninstalls, Windows apps. A new look & feel, smart filters, and additional helpers make removing applications even easier and safer. Process Manager features a new and optional tree structure view for better clarity and also displays SVHOST-based processes. SSD Wizard provides additional info that helps to prolong the lifespan of your drives and to enhance their performance.

  • What's the difference between Office 365 and Office 2019?

    You get the premium Office software with the Office 365 subscription plans: Word, Excel, PowerPoint, OneNote, Outlook, Publisher, and Access (Publisher and Access are only available on a PC). Office 365 can be enabled across various devices, including PCs, Macs, Android tablets, Android phones, iPad ®, and iPhone ®. Office 365 also comes with services such as 1 TB OneDrive room, 60 Skype minutes a month and support for Microsoft chat and phone. You get the new versions of the software with a subscription, and also receive updates as they happen. Learn more about Office 365.



    Office 2019 is a one-time purchase that includes classic PC or Mac applications such as Word, Excel and PowerPoint, and does not contain any of the features that come with an Office 365 subscription. One-time purchases do not have an upgrade option, which means you would need to buy it at full price if you intend to upgrade to the next major update.

  • How do I know my PC or Mac can run Office?

    By viewing the requirements, you can verify if your computer will support your Office version.

  • Will Office be identical on a PC, a Mac, and a mobile device?

    No. Office applications are designed to better function on each system and platform. The Office applications and version numbers available to Mac users can vary from those available to PC users.

  • Can people with an earlier version of Office open documents I created using Office 365 or Office 2019?

    Office 365, Office 2019, Office 2016, Office 2013, Office 2010, Office 2007, Office for Mac 2011 and Office for Mac 2008 applications can open your documents without further intervention. Customers using earlier Office versions would need to download and install a compatibility pack.

  • Is Internet access required for Office?

    Internet access is required for downloading and enabling all the new Office suites releases and all Office 365 subscription plans. Internet access is also required for Office 365 plans to control your subscription account, e.g. to install Office on other PCs or to change billing options. Internet access for documents stored on OneDrive is also required, unless you install OneDrive desktop app.To keep your Office edition up-to-date and benefit from automatic updates, you should also connect to the Internet regularly. When you do not connect to the Internet at least every 31 days, your applications will go into reduced functionality mode, which means you can access or print your documents, but you will not be able to update or build new documents. Simplify reactivating your Office software by reconnecting the Internet.



    To use the Office software, such as Word, Excel, and PowerPoint, you don't need to be linked to the Internet because the programs are completely installed on your computer.

  • What is the maximum number of Office licenses I can activate using the same Microsoft account?

    Users can activate 1 Office 365 Home and Office 365 Personal subscription, and up to 25 Office Home & Student 2019, Office Home & Business 2019, and Office Professional 2019 licenses.
