How to change my delete email account to my new email

Hi
Please follow below steps
- Login with your old account
- Add New Account with below steps
   Start->Settings->Accounts->Family & other users
                                    |
   Select Add someone else to this PC
Choose "I don’t have this person’s sign-in information", then "Add a user without a Microsoft account", OR log in with your new Microsoft account if it's ready

If adding a Microsoft account, just enter your new email and follow prompts
- Give Admin Rights to the New Account
   After adding the new account, click on it, choose Change account type, and switch it to Administrator
- Now you can sign in with new account

Hope this solution works
