I have now fleshed out the Windows Media Player section, available here.
- 6 additional visualizations (making a total of 16 packs)
- 183 skins (making up a total of ~314mb), including Beck
- 12 plug-ins
I’d also like to note that most of (if not all) the skins do indeed work on WMP 12 and Windows 10, though it’s not immediately apparent. Just go to View > Skin Chooser while in the Library view.
Download and enjoy. Greetz to windows-media-player.com and this archive.org collection for making it happen.
