Why? It works with win 10.

It actually caused computers i used defraggler with to run slower on windows 10, It's best to use windows disk optimizer in windows 10. Windows 8 and 7 have worked great with defraggler though and I have had 0 issues with it with them. Just stick to windows disk optimizer if using windows 10
