Windows 10: How to reset admin password

My father has recently passed away and since he has worked with computers his entire life while I mostly used them to play video games, when I got my PC he gave himself an account with admin permissions while he gave me a guest account since at the time I was a little kid, I didn't know what I was doing and wasn't really into programming or similar things. Now that he's gone I don't really have a way to install anything or run any types of programs on my computer since I don't have admin permissions nor his password, when I tried rebooting my pc or the cmd-utilman trick they both asked for an administrator's password (guess it was fixed). Could anyone help me?
