holy crap I just looked it up and there are supposedly 32bit only versions of windows 10. I thought for sure that ended with xp.
Running 64-bit XP was actually kind of rare
Technically it was just only recently that ms no longer has mainstream support for 32bit oses, as they only dropped that with windows 11.
Makes me think that might be the reason for valve choosing now to do this.
