Most of us are probably aware of Windows' big problem when it comes to design consistency ... it doesn't have any. That's mostly due to the fact that Windows 10 is built on decades of old code. While Microsoft is trying its best, there are still plenty of areas in Windows 10 that throw you back to UIs that were first introduced years ago. Here I'm pointing out four obvious old UIs that are still present in Windows 10 today. This list isn't limited to "legacy" UIs, like those first introduced in Windows 95. Everything up to Windows 8 is considered old UI in Windows 10, now that Fluent Design is a reality. Music control

The current music control UI found in Windows 10 was first introduced with Windows 8 in 2012 and is using Microsoft's Metro design language. While Microsoft's current design language is a spiritual successor to Metro, a lot has changed since the Windows 8 days, making the current music control element seem somewhat out of place.

Give it some blur, change up the icons, give it a dark and light mode, and perhaps even make it a little denser for mouse users, and you've got an updated music control that follows along with Windows 10's design. USB popup

Upon inserting expandable storage on your PC, a popup will appear asking the user to choose what they want to do with the device they've just plugged in. This is yet another UI that was first introduced in the Windows 8 days, and it hasn't been updated nearly enough to follow along with today's design language. In fact, the dialog itself still appears at the top right of the screen, even though toast notifications have moved to the bottom right on Windows 10. As a bonus, it'd also be great to see Microsoft update the scan and fix UI, something that hasn't changed in Windows since Vista. Windows 10 clean install UI
