Hope this is in the correct place. Windows 8 pro 64-bit. I am trying to find something better than Piriform defraggler. Usually Piriform defrag takes about 15 to 20 minutes to defrag the OS C partition. Auslogics is doing the same thing in 15 seconds. Not possible. When I look at the logs it says the defrag was aborted. WHY? Is it compatible with Windows 8? Or is there some setting I am missing? It's also telling me that my registry has over 200 bad files. This really worries me and makes me doubt Auslogics. There is nothing wrong with my registry. Thanks for any insight or where I should go for more detailed information.
