I wanted old school MS solitaire in windows 11 since the modern version has ads and extra useless features. I found that the Windows XP version works without hassle. Earlier versions aren't really different but I forget if I tried to run earlier versions. One quirk: however the winning animation is programmed, it takes almost 20 minutes to complete on a very wide monitor[1].

The score is a value stored in the Windows registry, the poster probably re-created (or imported from a previous export) the registry entry upon each Windows installation.
