It did have a decent run in the embedded market, especially before windows 2000 as it had a clean 32-bit codebase that was more stable than win9X. A lot of ATMs used it. You’d also be shocked what you’d find in the back IT cabinets of some older companies. A former colleague who now works at a defence firm sorted through piles of old manuals from 1980s era VAX/VMS hardware during an office move (even though it was public documentation, the bureaucracy of disposing it meant they still kept it and moved it).
I wouldn't be shocked at all. In the 90s I consulted for a couple of UK firms that used OS/2 - a training company I worked for used a (nightmarish) C++ compiler that only ran, very badly, on it. And I trained several batches of VMS programmers in converting to Unix.
Perhaps a more interesting question would be: "how do I create a localisation CD?"
