Wait, Did Apple's 'Liquid Glass' Design Steal From Windows Vista?

Is it Liquid Glass or Windows Vista redux? 

During WWDC, Apple debuted a major redesign for its software, including iOS and macOS. But Microsoft users tuning into Monday's keynote experienced some déjà vu, and pointed out the similarities between Apple's refresh and Windows Vista, an OS from nearly 20 years ago.

Apple's "Liquid Glass" redesign aims to creates a translucent and polished user interface. Windows, toolbars, and buttons are transparent, "making the display feel even larger," while bringing icons to life through dynamic color reflections, the company says.

Although the redesign is meant to be new and fresh, some old-school Windows users experienced flashbacks. Apple’s approach looks and sounds very similar to the Windows Vista “Aero” interface, which also adopted a glass-like transparent design when it debuted in 2007.

“Apple's Liquid Glass = Windows Vista Aero 2.0,” one user on X/Twitter said. “This is nostalgia slathered in Cupertino polish.”

“Time is really a flat circle,” another user said. 

Aero stood for “Authentic, Energetic, Reflective, Open." Its transparency design element persisted into Windows 7, but Microsoft retired the Aero interface with Windows 8 and 10. 

To be fair, Apple’s redesign looks far more modern, and was designed for mobile devices, including the iPad and iPhone, not just PCs. Some observers also expect Cupertino’s approach will be better since Apple is promising all the design elements can dynamically change in real-time, whereas Microsoft’s Aero interface was more static.

Apple plans on releasing public betas for iOS, macOS, and iPadOS next month before an official release later in the fall.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
