You can just turn it off.
WP6.2 on DOS on a 21st century machine screams along. I run it occasionally under IBM PC DOS 7.1 (the FAT32-capable version) on bare metal and it's wonderfully rapid.
Quite often solicitors have stuff on 3.5" or even 5.25" floppies that need read, converted from WordPerfect into something modern, and delivered as maybe a PDF or Word Doc.
Fortunately, solicitors tend not to be short of money (that they bill their client for) so they can often find "a guy who knows a guy" who can get that precious floppy onto a USB stick. Occasionally I am the guy who the guy knows, and it buys me the odd case of reasonably-priced wine.
Ongoing contracts (e.g. life insurance policies may last 40+ years). I did work for an insurance company once, and they had active policies started prior to 1940. There were electronic documents which dated back 30+ years.
While completed transactions may only need records for a few years, ongoing assets and contracts need documentation held for much longer.
Probably stuff to do with property ownership.
Last PC I saw in daily use with floppies in daily use was about five years ago.
