Other Functional 90s Software
Count me as another who still occasionally uses a an actually paid for version of PSP 7.
The other utility still in (far more) regular use is LeechFTP. You have to be a bit careful with this one - you can't just tell people to go and grab it from the web, because most of the versions I've seen out there are bundled with stuff you, er, don't want. However I still carry around a ZIP of 1998 vintage that is happily installed on various Windows boxen, including this Win10 one, and working entirely as designed - including its occasional dialogs in German :)
