Desktop Operating Systems and Recovery

Brand new HP but since I cannot get past login screen I have no error messages to share.  I have gone through at least 5 system resets and I am close to giving up.  I should add that I am 81 years young and very, very unhappy with this new computer.  BTW, I am contacting you using my old computer.  I believe the biggest problem is having to login using Microsoft account and I have done everything possible to convince MS that I am who I am.  I was able to create a new account using this old computer but of course MS can't seem to grasp that concept on the new computer.  Do any of you know of a way that I can bypass having to use MS to logon?  I have never had to do that before on other computers.  I truly believed that doing that system reset (5 times) would have enabled me to correct the issue but it remains.  HP agents don't understand what I am trying to explain and I realize I am probably not making things clear but I don't know how else to explain it.  If anyone can help me I would be most appreciative.
