Thanks for sharing the details, Jeff!
If you want a hassle-free way to get a variety of visualizations for WMP Legacy, start with WMP Goodies: it’s the most comprehensive collection, and many of the old classic visualizations are still packaged there.
Just note that, some visualizations originally shipped with older WMP versions (like Musical Colors, Ambience and their “families”) were removed in later versions (e.g. after WMP 10/11). Even if you find them online, some old visualizations may not work properly, partly because modern Windows (Windows 10/11) + WMP Legacy may have compatibility issues.
Because many of the downloadable visualizations come from unofficial archives/community projects, you should be cautious: some DLLs may be outdated, unsupported or carry risk, always use trusted sources when possible.
Best regards,
Kimberly
