GP Help need. Trying to restore shutdown on start?

Hi,

I have two users on this pc. All users are local and not in a domain.

I do not have shutdown disabled on the administrator but the shutdown is disabled on the other account. The other account is a standard user account.

I have a GPO specifically for the non-administrator account. The username for the account is "guest-".

This is what I have try so far.

1. open the GPO "gp guest-.msc"
2. go to Administrative templates/ Start Menu and Taskbar / Remove and prevent access to the Shut Down, Restart, Sleep and Hibernate commands.

3. I had the setting enabled but now what the guest to be able to shutdown the computer.

4. So I put setting back to "not configured"
So check that setting in computer configuration is "not configured"
5. open cmd and do gpupdate /force

6. group policy is updated and restart pc.

I sign in to "guest-" and can't shutdown the pc. What's going on?

Thank you for the help.
