I installed Windows 7. I understand that the user that is created first is considered an administrator. However, I did not want that user to have administrator credentials, so I removed them from the administrators group. Now, I need to run applications/installations with administrator credentials, but am unable to do so. I have tried all of the conventional methods, but every time I try to access something blocked by UAC, I get a prompt to enter an administrator password. However, there is no box to enter the administrator password. Thanks in advance for your help!
