Well, it's not that the latest Office is that much different in this sense... just open Word, add a tab stop, double-click on it and you get a dialog box that probably was almost identical in Word 6 on Windows 3.1. Not that it looks bad or anything, it's perfectly appropriate IMHO. I still dream of getting back menus in Office, now some functions are so hidden that if you don't use them often enough you always lose ages to find them once again.
Clicking the "100%" next to the zoom slider gets another Word 6.0 refugee, complete with nice pixel art 4:3 CRT.
In Windows 10, Wordpad and Paint can both bring up the classic Windows 3.x colour picker Window, complete with the inscrutable Custom Colours bit. Although Wordpad is gone in Windows 11 and I don't think the Windows 11 Paint has the classic picker. It still (IIRC) has a colour arrangement in its new picker that is based on the classic pickers default colour set. Which were chosen because they dither nicely to 16 colours with the Windows 3.x dither algorithm.
