Windows 10: Bought a Win10 laptop from a guy,how to change the login and password?

Bought a 2-year-old Dell Inspiron with Windows 10 from a fellow. He gave me his password (actually it's a 4-digit PIN) with it of course, and it works fine as long as I use his PIN, he said that's fine with him.

But what I really want to do is eliminate the need for a password or PIN at all. And I wouldn't mind changing the account name that comes up in the middle of the screen when I first power up the computer, with my own name. Right now it's a string of meaningless numbers.

I've googled around and found how to CHANGE the PIN, that's progress. But I'd rather get rid of it entirely, When changing the PIN, I tried to simply enter nothing and hope that got rid of the need for it, but no luck. It kept balking and telling me to type in a PIN. Finally typed in a new one I'd remember, typed it again to confirm, and now I have to type that new one in then I power up.

How can I get rid of the need for a PIN at all?

And how can I get the computer to display my name instead of the string of meaningless numbers it shows in the screen (I think that might be an administrative account)?

Thanks all!

Just bought PC and can't login


I just bought a new Samsung laptop. Went through the setup. Skipped the part on creating a microsoft acount. Set my password for the laptop. Played around for a while and every thing worked great. Shut down PC. Got on this morning and couldn't log in. I know what my password is but I tried every other password I have ever used and can't get in. Booted to Bios to changed priority to boot to USB so I could hack the password, but there is no USB option. Went through all the articles I could find on the web but found no solution.

Any Suggestions? Is it really asking me for a microsoft account login instead of my laptop login?

Thanks

This is solved. Moral of the story is you must setup a Microsoft account or you can't login. My old laptop was Win 7 and that was not the case. The fix was to do a factory restore by booting with F4 held down. Then go through the setup and include a MS account.

 

Password issue

After going through the steps to make a new password, after a week or two, my login credentials are no longer valid. I'm forced to make a new password all over again. It seems to happen if I don't login in a certain period of time. Does our passwords expire???
