There appears to be 2 questions here;
1. Creating a local user account with administrator rights
2. Making the Desktop of this new account the same as the Live account
I have been experimenting with these questions and had no dificulty performing the functions. I have Classc Shell, which allows me to move around the PC very easily, and I have not installed the latest MS Important updates (39) since February. These are not critical updates, so I chose to ignore them. This lack of similarity between our PCs may make a difference.
I will assume that you do not have Classic Shell installed and proceed from that point.
Boot your PC using the account with Administrator rights.
Press the windows Key + C to display the Charms Bar on the right side
Select Search, make 'everywhere' the default, in the window type 'user acounts'
From the menu select 'add, delete and manage other user accounts'
From the menu select 'Add an Account'
This is the critical window 'How will this person sign in?' Look at the last entry on the page. "Sign in without a Microsoft account (not recommended)" Select this option
From the new window select 'Local Account'
From the next window, complete the options as you desire. I set up a Guest account with no password.
From the new window select 'Finish'
The window should advise you that this new account is set up. It is a local acount without a pasword required and no administrator rights.
Press Windows key + C to display the Charms Bar
Select Search and type 'User Accounts'
Select 'User Accounts'
From the new window select 'Manage another account'
Click on the account you just created
In the new window select 'Change the account type'
Select the circle for "Administrator' and click on 'Change Account type'
A new window should display showing that this new account is a Local account with administrator rights.
I did not mean to treat you as a newbie. I realize that you are able to set up and change account types, but I tried to make the process very basic. You may take other ways to achieve the same results.
Log out from your Administrator account and log in with the new Guest account that you just created. What displays? This will determine the next steps.
Post back please.
