How do I change original user in Windows 10 at out-of-box point?

[rogerDphillips]

Recently inherited from my elderly parents a new HP All-in-One computer that had been set up with their account in Windows 10 at the out-of-box point. How do I go about getting rid of their account as the original user and now set up me as the original user. I have looked at the 'change account type' options but that seems not to be quite right. Or am I missing something? In my attempt at problem-solving, I've also rec'd a display-message, something about Microsoft having trouble recognizing my 'family.' Suggestions? I am not a regular Windows user so shooting the dark a bit.

I'm guessing you want your personal account as the main admin account?
