I’m a bit confused by your criticism. Windows 7 came out in 2009, Windows 8 came out in 2012. And your criticism of Windows 7 is that it doesn’t run great with modern hardware? Microsoft not optimizing an old operating system for new hardware when it’s focusing on a new version, to me, isn’t a reflection on the quality or design of the old operating system. To me that’s like criticizing DOS for being limited to 640kb of memory. It was designed for the hardware available at the time.
