I have a think pad w510 laptop that had recently been upgraded to win 7 enterprise. Every time i install something or change a setting, it asks me to allow the program then to type a username/password. After that i get an annoying error saying " the requested operation requires elevation". does that mean that i typed my username/password incorrectly or am i not an administrator? I can change the uac settings because it will not prompt me or allow me to do so.
