You will never have a "Confirmation" or "Permit" button step for your admin tasks again while logged into your administrative account.
If you wish to use a limited account (which is suggested), you can then just create a standard (limited) account and use it for most tasks (have the admin account passworded and login to it as needed or just do the old fashioned right click > run as *admin account* > *type password*).
If you leave UAC enabled (and use a limited + passworded admin account), the standard account will behave similar to linux, in that when you are not logged in as root (admin account), a popup will appear when you try to perform administrative tasks and then you enter your admin password, it then completes the administrative task (you remain in the limited account).
