Nostalgia, indeed.
It goes even further back than that. If you dig hard enough you can find original W95 styling and 3.1-era icons laying around. Or at least could, as of W7. No idea past that since W8 and up is a dirty word around here and I can't be bothered to check the lone W10 "runs a handful of $$$ business apps" PC right now.
Some might think the Windows GUI subsystem has been neglected for 20 years. The funny thing is the older control panel apps are the ones that tend to work the best for things other than nagging for activation and showing ads....
