Funny, the author considers Windows 95/2000 the pinnacle of usability but then includes a screenshot that illustrates one of the issues with it: the start menu being able to contain folder within folder of complexity, each triggering its own popup. One wrong mouse move and you could start over again. Having said that, the UI was incredibly clean and didn't contain too much marketing crap. Though even in W95 Microsoft just had to put an MSN (Microsoft Network) icon on the desktop - not related to the messenger or news site but their own proprietary alternative to the internet which they abandoned soon after - thank god.
