I've provided a link that explains the installation but know this. It is limited to what the author has included in the pack. Stardock has a tool called Object Desktop Manager. It requires a subscription but included are a host of programs that when bought separately cost over 200.00 USD. The subscription itself costs far less, about a quarter of that. The custopacks, like I said, are limited to what the author included. With Object Desktop Manager there is no such limitation and you can mix and match every style from cursors to icons to the visual style itself. Chief among the 'themes' is a program called WindowBlinds, the visual style, browse our galleries and you'll find literally thousands of different 'skins' or styles to choose from.

Good luck which ever way you go.
