I am looking for any information on how to find the admin password on a computer and after that ways i can go around the system and get other useful information i have a meterpreter session running on the windows machine but it is in a non admin privileged account. Also any helpful tutorials on how to use the meterpreter as I am new to this and only knowledge I have is what is provided when you type "help" however I am sure there is a lot more.
