"Windows NT/9x/2000 represented the high point for aesthetics."

I hope you are aware, that this is highly subjective?

(and maybe nostalgia related?)

Because I don't know any person who likes it, who didn't use it back then a lot.

edit: unsurprisingly notaware it seems. I advice to make a test : ask any person who did not use this aesthetic back then, and see if you find anyone who likes it

otherwise each to his own
