Because life’s too short

To sit around waiting for your PC to start

 

Too many programs trying to run automatically can really slow you down.  System Speedup displays a list of applications that run on start, and lets you postpone or stop the ones you don’t need. It will even alert you to ones that slow down your system starts.

Keep your device clean and lean

Over time, your hard drive becomes cluttered. System Speedup scans your PC for all the stuff it no longer needs – system cache, temp files, internet junk, and unnecessary user data. It then clears it all, cleaning your PC and freeing up disk space in the process.

Freshen up your browser

There’s some stuff browsers can’t delete by themselves. System Speedup removes all online traces and temporary data from every browser, and then optimizes the browser database to keep your disk clean.

Clean your registry

Your registry is a critical behind-the-scenes player on every Windows machine. But over time, invalid registry entries or leftovers from uninstalled software pile up. System Speedup can analyze and clean up any registry problems you have.

Relax with real-time monitoring

If thinking about disk cleaning and optimization gives you a headache, just use System Speedup’s real-time monitoring software for a reminder to clean your machine. You can customize the alerts to suit your PC.

Speeding up your PC never looked so good

Intuitive

With an elegantly simple layout and easy-to-understand interface, System Speedup makes keeping your machine in perfect condition a pleasure rather than a chore.

Informative

Most similar programs just do their thing, leaving you none the wiser. System Speedup clearly informs you which files can be removed from your system and how much space you saved.

Avira Optimizer for Windows: Free computer cleaner and PC optimizer

Don’t waste your time waiting for your computer to start up – our computer cleaning software for Windows gets your machine to start faster, often by more than 25%. Over time your Windows computer, laptop or tablet gets clogged with junk files, temporary data, bloatware and more useless data. Daily clutter, too many start-up items, and a corrupt registry slow down the system performance. Our free computer cleaner analyzes and cleans the system with smart PC cleaning tools.

 

Advantages using our PC optimizer

We have 30 years of experience in developing software that enhance the digital life of our users. Our security and clean-up tools Made in Germany protect your machine, increase your privacy and improve the overall performance. Your PC cleaner software advantages:

 

Faster and more stable for turbo performance

Our PC optimizer finds problems within your Windows installation and registry, shows where they are coming from, and enables you to reduce or prevent these issues in the future. Our Windows cleaning software cleans the clogged or corrupted registry to speed you up.

 

Often more than 25% faster start up

A long list of programs starting on boot slows start-up time and you have to wait. In many cases, most of these programs are not used all the time, and can just as easily be started when needed. Our free computer cleaning software monitors the list and speeds up the process through clever management. The result: Your PC starts faster, often by more than 25%. Our Startup Guard makes sure that the load time stays as short as possible.

 

PC cleaner: Free more disk space and get rid of unnecessary data

For best performance, your hard disk should never be completely full. Junk and temp files, internet junk, system cache and more data fill up your disk space. Get rid of all unwanted files and increase free space and performance.

 

Better privacy protection: Delete internet traces and temporary online data

Browsers save many data automatically to improve the user experience and, for example, load previously visited websites faster. You can tell your browser to delete the browser history and cookies, but they can’t delete everything themselves. Our Windows clean-up tool removes temporary data, hidden personal data, and online traces from every browser you use. Deleting hidden personal data increases your protection, as hackers cannot access them anymore.
