I have 2 XBMC installation on a Win 8 and Win 10 PC
I spent the past couple days tweaking this skin to where I’m really happy with it. I installed kodi on the 2nd PC (Win 10) used the Xfinity backup and restore and got everything back except the tweaks I did for the skins.
All of my wallpaper settings resides on the NAS FWIW.
