That's another rhetorical question, by the way :) Huh? If you mean Openelec beats Kodi on Windows, how is that? A bunch of them will be missing in Openelec compared to the Windows OS.
If you have installed both, just check the settings page.
Although Open ELEC or Kodi Buntu would be great, some of the hardware in my HTPC (a re-purposed Lenovo Think Centre) doesn't have Linux drivers.
Maybe my next project based on a NUC or similar with 4K video support.
Kodi on Openelec and Kodi on Windows is night and day.
