macOS does not and never has had a good strategy for handling minimizing windows. Keep in mind that prior to Mac OS X, you couldn't minimize windows at all, you could only roll them up. When OS X added the dock, they made minimized windows go there. Except, the Dock is an icon grid, so there's no way to see window titles, and the windows themselves are so small that it is difficult to identify them at a glance. Making things worse, the Dock is also a place you put app icons, so now you have an icon to show all your non-minimized app icons, right next to all your minimized window icons.

Meanwhile, Windows had minimize since version 2[0], except for whatever reason windows minimized to desktop icons, and there was no desktop folder. They'd known they'd invented a worse version of Mac OS, and in Windows 95 they made sure that there was not only a real desktop, but also a list of all open windows. This design was so successful that the only major tweak that stuck was merging the taskbar and Quick Launch[1] into something that superficially resembles the OSX dock, but is just plain better[2] because clicking an app icon actually shows you all the open windows.

[1] Strictly speaking you could put anything in Quick Launch, but only apps go in the Win7 taskbar

[2] Oldschool NeXT users will point out that in NeXTSTEP, minimized windows had an actual title on them, and the app icon instead of a screenshot of the window at tiny scale.
