I haven't touched a Windows machine in the past 15 years and is shocked to read in this article that running DOS apps is no longer a feature of Windows. From my childhood they were as intertwined as the peanut butter and jelly on a de-crusted wonder bread.
You misunderstood the article. It is not a feature of 64 bit Windows, but it still works on 32 bit x86 version. Exactly how it was 15 years ago when Windows XP x64 debuted.
