In Windows 11 you're only 3 clicks away from a Windows 3.1 dialog box:
ODBC Data Source Administrator (64-bit)
Configure > untick "Use Current Directory", Select Directory

Gotta love that the disk and directory picker survived 20-30 years.
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.
