i have three users on my start up page 2 administrators and 1 standard user. For the 2 administrators users i have forgotten the passwords. For the standard user i still have access to and can logon to the HDD but can not access any program files or even do any windows up dates due to USER ACCOUNT CONTROL i've been trying to access threw COMMAND PROMPTS but im not too familiar with the prompts terminologicy. and have gotten very frustrated with the CMD PROMPTS i know that if i can access threw the CMD i can remove the password for one or both of the administrator accounts an reset them threw the user accounts in the control panel i just cant seem to get past the UAC asking for my administrator password (WHICH I HAVE FORGOTTEN) nor can i seem to master the CMD PROMPTS either. also i no longer have the windows 7 disc which i used to install windows on the HDD. ANY & ALL HELP WILL BE GREATLY APPRECIATED & ACCEPTED THANX.
