NEW: O&O Defrag 30 Server Edition for Business – Save your company time and money

With O&O Defrag 30, we have raised system optimization to a new level.

Do you ever wonder why your systems get slower? Lagging performance on workstations and servers, slow start times…and maybe you wonder why you have to replace some hardware relatively quickly? It’s most likely due to fragmentation – Windows splitting up every file you and your coworkers and employees save into fragments, spread across the storage volumes.

Regular defragmentation of hard disk drives and solid-state drives in business servers and workstations enhances performance by ensuring efficient file organization, leading to faster access times and improved overall system performance. And due to less read/write actions, you can extend hardware life by up to 40%.

NEW: Boot-Time Optimization and Improved O&O IntensiveOptimize

The new Boot-Time Optimization offers fully automatic optimization before Windows actually starts, ensuring that all files can be optimized. This particularly applies to critical system files that are locked during Windows startup and can cause significant performance losses.

With the revised O&O IntensiveOptimize, we also offer ambitious users the opportunity to optimize their system in their own Windows environment. Also with full access to all user and system files.

NEW: Intuitive User Interface

Brand new in O&O Defrag 30: As part of this expansion, the modern user interface of O&O Defrag has also been revised and simplified, allowing automatic optimization in the background to be activated with a single click. The integration of O&O IntensiveOptimize, the new Boot-Time Optimization, and the existing and new tools has also been significantly simplified.

Now available over a Network Management Console

O&O Defrag can now be managed across a network! Roll out, install and manage the performance of your machines by deploying O&O Defrag over our RMM Software, O&O Syspectr! Over an intuitive dashboard with a whole range of monitoring and management functions, you can not only manage your system performance, but also be automatically notified of any issues. Any time, anywhere. All you need is an internet connection.
