Change original administrator account

I have purchased a used Asus laptop that already has Win 10 installed on it from the original owner. All of the settings on the computer are linked to that owner's Microsoft account and administrator account. Is there a way for me to change the administrator information to my Microsoft account and email? I can log in using the old owner's password to access the administrator account, but I don't see any way to change the account to my information. If I create a new user account and make it an administrator account, when I log in using the new account, there is no access to any of the apps I need from the original account. Thanks.

I don't have the answer to your question except..................

You can change the old owner's password if you want. Use this tutorial :

Hello and welcome to the TenForums :)

This seems an odd arrangement, I would have expected the previous owner to have done a reset and returned the laptop to factory settings so you have a fresh system to start with.

You say you want to stay with the original owners account because of access to the apps. As you know the password, one solution to this would be to convert the original owners Microsoft account login to a local account and give this account a new name and password for yourself.

Afterwards you can then switch it back to a Microsoft account and use your account details. Follow this tutorial:
