It's hard to look at Apple's new "Liquid Glass" aesthetic and not think about Windows Vista, Microsoft 's much-maligned OS which also touted transparencies and glass-like effects as a bold new vision for computing.

Microsoft has officially poked fun at Apple's Liquid Glass UI overhaul by sharing images of an old Windows operating system version.
