I think that would be Windows 98 SE and WinXP already broke some compatibility with really old stuff. But yeah, it offered some good balance of that regard as it can run on relatively modern hardware (although even in 2019 it was already a challenge installing it on random new PC - and I worked for a place where we had maybe 300 WinXP production machines we couldn't migrate because of legacy stuff used).
