Basically I want to prevent non administrator to access the whole drives.
So I right click and delete everyone and authenticated users from list of permissions
So only system and administrators can access that. The rest cannot. The thing is I am administrator.
So why can't I?
I also set my self as owner.
Some comment says that I am showing permission for system account.
I upload another screenshot. The administrators have same permission except special permission. I don't know what special permission means
