A stable version of Windows 95 supporting new hardware is what Windows 98SE was by and large - and I know a lot of people who still swear by it - I dont know if you have ever installed it on a new super PC but it is comically fast, especially to boot to desktop.
I haven't, but I've wanted to try it ever since I read about how Windows "minimises" open windows by simply moving them to X,Y coordinates that are off the screen. Apparently in 9x those coordinates are close enough that, with a suitably arranged modern multimonitor setup, you can actually see all the "minimised" windows piled atop each other in the corner.
