I found this old thread via a google search after seeing that The War Within’s minimum OS requirement in the Battle.net app was listed as Windows 7.
I thought “no way is that true” and searched.
Reading the first page or two, I want to humble-brag that I was still using Windows 7 in 2024. A six year old install in fact. Nerd Pride!
I don’t know when WoW stopped working for W7, I did not play from June 2021 to March 2025… Oh wait! Partner and I bought a month of time around Dec 2022 for winterveil and retail was still working on W7 then.
Edit: remembered install was from 2018 not 2016, hence, six year old install of W7.
