I can see this being a fail.
My folks, octogenarians, they've been using PCs for about 15 years. Windows 2000 and Windows XP. Imagine they go to the store, I'll be generous and say John Lewis and purchase a new desktop with Windows 10 and S mode deployed out of the box.
They set this up and try and run their beloved "Spider", some card game that I can't fathom but made by Microsoft. The version in the App Store is the current version, but not the one *THEY* want.
Since this doesn't do what they want my guess would be to return it, because:
1) It's new
2) Doesn't meet the requirements
3) I'm not going to talk them through some random Windows 10 SNAFU, because it will be complicated
4) I'm not getting a plane and flying a 12,000 mile round trip to fix MS Windows and MS aren't going to repay my time/costs
