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

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.


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.
