It sounds like you are in the built-in Administrator
account. Does it have the exact name of Administrator
? You will not have UAC bugging you or that option in Power Options in this account since everything you do is already elevated to allow you to do it.
Nothing to worry about. This is normal while logged on to the built-in Administrator account. For example, the option to Require a password on wakeup yes/no
is normally grayed out until you click on the Change settings that are currently unavaiable
link. You should be able to make this change.
