Why O&O Defrag 27? 

🚀 Intensive Optimization: The new O&O IntensiveOptimize 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.

🎯 Remove superfluous programs: Programs that are no longer used can pose a security risk. They are definitely wasting disk space. You probably won’t need a 2011 tax return program anymore. But do you even know it’s still installed? O&O Defrag 27 now clearly shows you all installed programs. And with one click, you can easily uninstall the ones you no longer need. This saves storage space (important for SSDs) and increases your security.

🔧 System maintenance of your data volumes: O&O Defrag 27 checks your hard drive or SSD for inconsistencies that can lead to problems. The component memory and the Windows system files are checked for errors. After the check is complete, O&O Defrag will show you whether and which errors were found. Most errors can be corrected directly with the repair function.

🔍 Free up storage space: Over time, more and more ballast accumulates on a PC. Temporary files, internet cache and the like can take on considerable proportions. This can lead to a storage space problem, especially on modern SSDs. And backups also take much longer than is actually necessary. With the improved O&O DiskCleaner in O&O Defrag you put an end to files that are no longer needed
