Windows 10 password problem. [View all]

I did a bit of a search, and I have a question in to the eBay seller, but I thought I'd also try here. Thanks in advance if anybody can help me.

So I bought a refurbished Dell with Windows 10 on eBay. I know, I know, but I just cannot stand Windows 11 and I'm going to start using the computer that has that on it, dual boot with Linux, strictly as Linux. But I'm not familiar with Linux yet, so I got something cheap that I am familiar with and figured had to be better than Windows 11, even with the issue of no security updates, which, on a side note, infuriates me.

Anyway, I was setting up the basic stuff the way I want it, and some of it was giving me trouble, and that's my excuse for neglecting to put a password on it. I was able to access it with no password whatsoever.

So this morning it tells me my password has expired and I need to change it, and won't let me log on until I enter my old password and my new password. Which would be just fine except that there is no old password. It had no password. Yet it wants the non-existent old password and I am completely locked out.

I don't have high hopes that anybody else has had and solved this problem, because anybody else would probably not be as dumb as me and put a password on it right away.
