Windows 10: How do I reset adminstraor to local user without having adminstrator password?

4 years ago a former friend "helped" me set up my new computer. I later realized that they used their phone number to build the administrator account, and they built me a local user account. I don't have their password, so I can't fully use my computer. Can't download applications for instance. Is it possible to reset the administrator account without the password? ... or am I going to have to wipe my computer and re-install windows? thanks

If I do a reset this PC, can I setup local user password network share

I was wanting to share files on the LAN but it requires a password. If I do a reset, sign in with a PIN and my Microsoft account, how can I setup a local user password so that I can share files on the LAN?

Lot of work just to do that one thing.

Anyone have a step by step? There is apparently an unknown local password set and it can not be changed. I login with PIN on all my PC.
