O&O Defrag Professional Edition for Windows

User Reviews

• My Samsung is in love with O&O

  Ibracadabra009December 14, 2012

  Pros

  I tried PerfectDisk 12.5, Diskeeper 2012 and I always went back to O&O. My system is way faster with this program, just use for start Space and then Complete/NAME and you PC will be in form :D

  Cons

  I don't know what's better defrag in background or screensaver defrag, i can't find that in help. But for me that's not Cons.

• Very Confusing Options/Settings!

  scottls59901November 20, 2012

  Pros

  A good price, and Lots of Options!

  Cons

  -Trying to figure out which Settings & defrag Options, is Very Confusing!?- Using the Default's...- My system is slower! - I wish they had a Forum, where you could ask other Users about Best Performance settings...!?

  Summary

  My system was faster with free Defraggler, but No MFT boot defrag. O&O would probably be faster, If I could just set it up properly...!?

• Version 16 Is Buggy

  -Surrey-September 22, 2012

  Pros

  New History section in version 16 comparing defrags before and after.

  Cons

  Version 16 is buggy.

  Summary

  Been using version 15. Installed and used version 16 awhile and it is buggy. Version 15 used to automatically analyze disks when program started. Now in v16 you have to manually click Analyze button to analyze each disk, before and after a defrag. When you run a Stealth defrag, after it finishes, it states, for example, 14% degree of fragmentation. But then after you click the Analyze button, after it finishes analyzing the disk, it states 85% degree. Shutdown function after job completion no longer works. External hard drives clusters appear in grey instead of colors (internal hard drives clusters appear correctly in colors) Defragmentation speed is the same as v15 despite developer's claim of a 40% improvement. Reverted back to version 15.

• Best out there but serious drawbacks

  jackandcicelyJuly 21, 2012

  Pros

  Windows 7 version sweet with perceived improvements in speed and effectiveness over Microsoft defrag.

  Cons

  Under Windows XP Professional (on PC and laptop)similar improvements not noticeable. On power down, both computers hang waiting for OODTRAY to finish and frequently power off is only achieved by forcing the program to finish, or sometimes holding the power off button in for 5 seconds. This is just unacceptable. Uninstalling is exceptionally difficult with neither the Control Panel nor the manufacturers Uninstall working, aftermarket uninstallers also do not remove it effectively. Manual removal seems to be the only way. Fatal flaw under XP.

  Summary

  Excellent under Windows 7. You'd have to be mad to use it under XP

• Cannot uninstall

  S_T_ANJune 9, 2012

  Pros

  Easy to download in the first place!

  Cons

  Very slow in comparison to some other top quality progs. Not the best interface by any means. Cannot uninstall easily. Just a pain overall.

  Summary

  It is all to messy and difficult to sort out - even the uninstall side of things is made virtually impossible to achieve (and the only reason I say "virtually impossible" is that I intend to find a way, but obviously not with the help of O&O!)

• Works great and at 1/2 the price of some others

  bdoggaustinSeptember 26, 2011

  Pros

  Fast and effective (I can definitely tell a difference after it has run)

  Cons

  If I had to choose one, it would be that there are not very many custom options (ie defragging methods, not that I would know what to choose anyway)
