I recently installed Windows 7. During installation, there will automatically be a user with administrative privileges. After completing, i created another "Standard User" as I wanted to limit other users for accessing all things. Then i opened the Built in Administrator account (net user administrator /active:yes). I deleted the account that i had created during installation of windows. Then I disabled the original administrator account (net user administrator /active:no) Now i only have Standard user account. whenever I try to open anything 'as an administrator', there will be a prompt in dimmed screen, asking for administrator password and click to yes; but there is not any place to enter the password. How can I fix it? Please Help Thanks in advance!
