NEW: O&O Defrag 27! Introducing O&O IntensiveOptimize, taking System Performance to a new level.

The new O&O Defrag 27 is out now and brings System Optimization to a new level.

Our new O&O Defrag 27 is now available!

Optimizing your computer not only means it operates at optimum speed and efficiency, it also means it will live longer. Deploying O&O Defrag saves you time through increased speed, and money through decreased wear and tear on your hardware. We have further improved O&O Defrag for you with some great new features. The new O&O Defrag 27 takes system optimization to a new level.

NEW: O&O IntensiveOptimize

The new Intensive Optimization (O&O IntensiveOptimize), now available in the Modern UI of O&O Defrag, is the fastest and at the same time most comprehensive optimization for Windows disks to date. A separate and exclusive instance of Windows is started, in which only O&O Defrag runs and can therefore not only exploit the maximum system performance for optimization, but also have access to all files at the same time. Regardless of whether these are system files or files exclusively locked during Windows operation.

NEW: User Interface

Brand new in O&O Defrag 27 is an entirely revamped interface for an even clearer and more intuitive user experience.

The number one cause of slow PCs

The Problem: Every file system is fragmented. This means that over time, files will no longer be filed consecutively but, instead, be scattered across the computer’s entire storage area, slowing down access to these files. This problem doesn’t just apply to hard disks but to SSDs as well. Over the course of time SSDs save file fragments over more memory cells than are necessary. This, in turn, leads to a continuous slowing down of the read and write processes, just as we experience on hard disks.

The Solution: With O&O Defrag 27 takes system optimization to another level. You can simply install the program and let it do its work. It will intelligently carry out whatever is needed on your PC on its own. O&O Defrag 27 will configure and run all settings automatically, according to the specific requirements of your system. Maximum performance practically out of the can.

Version 27 for automatic speed and monitoring! And should you wish you can of course manually setup, configure and schedule the optimization of your system yourself.
