Hi, I am the only user and administrator, this is shown in all settings, yet I apparently cannot do anything that requires administrator’s rights, e.g. - I cannot change the ‘hosts’ file. If I edit directly, cannot save, for not having permission; if I edit elsewhere and try to copy back, the ‘paste’ option is grayed out (the file is not flagged as read only, of course). - I cannot open the ‘manage’ option in ‘My Computer’. Nor can I run any program as administrator, e.g. notepad, Microangelo, or cmd. All open readily as ‘normal’, none as administrator. The elevated command prompt would not start from Win+X either. My only hunch is that all ‘administrator’ per se is somehow disabled; the system checks on the privilege but never recognizes. If, so, where is it done? Corruption or absence of which file or registry item may cause that? Of course, the solution may be something entirely different. Thanks a lot.
