I was recently pointed to a version of Steam that works on stock WIndows 7 that is newer than the official 2023 EOS version, or the previously known 2024-09-18 beta. This client is dated 2024-11-08 (or 07 in some timezones even though the date looks like it should be static) and seems to be a beta of some sort for Windows 7. So I obtained it and archived it.
Outside of our Steam archive, the only other version I could find searching online is the client from 2023 and I don't want another XP situation where the 2019-01-04 client was just gone for a while, and the latest that could be found online was the 2018-11-26 client.
Here's the link to the client with instructions on how to install and use it.
