Windows 10: standard user account and drive formatting

I am not suggesting that this would explain the problem but using that methodical procedure might help avoid confusing the issue by allowing an inconsistency to slip through unobserved while you are trying to fix things.

{I am adding that linked post as a Wiki article next month so do let me know if you have any comments about the procedure or its explanation.}
