We still have handful of those around at work. 2000, XP and maybe some embedded variant of 98 too still somewhere. They are controlling some non-critical but still useful industrial stuff with stupidly large price tag to replace.

Specially XP is still going to be around for quite a while in industrial settings where the production line is controlled via single computer and replacing it would mean replacing the whole line with price tag potentially in millions. And those aren’t even that old machines, their planning and manufacturing just takes “a while” due to certifications and everything.
