You may have your MCE to autologin using a "Media Centre" system user account, and then want it to autorun Media Centre and go straight into Live TV (as most UK set top boxes would operate - Live Tv first then menus if a menu button is pressed). OK heres how to do it via the Registry RUN key of the CURRENT_USER.
Live TV use HKEY_CURRENT_USER\Software\CurrentVersion\Windows\RUN) by creating a new EXPANDABLE STRING value. (Faster than putting into STARTUP folder of Start Menu)
