Sometimes the computer owner is required to change the permissions of users registered in the system, for example, to change the computer's administrator.
This can be done using standard Windows.
Click "Start", go to the Control Panel and select "User Accounts".
Seeing your account management window, click "Manage another account."
Select the account where you want to give administrator privileges.
Click "Change account type", and select the "Administrator". Confirm the changes.
In the same way, change the type of the account in which you want to take away administrative rights.
Restart your computer (or reconnect to the system).
