|I believe your PC has you, Jodie as the Computer Administartor with a lot of RIGHTS to make changes in your Computer settings. |
If you want to 'relinquish' the Admin title, you must first make someone else the administrator.
In Control Panel > User Accounts
Create a New Computer Administartor Account and setup a password.
Next you enter the PC with that Admin Account and Change your Account to Jodie like you did before.
