why is my guest account the only admin user?

[annihilator516]

I have six user accounts on my PC, i have a big family, but one of them can't login because "The Group Policy Client service failed to logon. Access denied" error message pops up and we are sure the password is correct. Also the guest account does not have a password it just logs in and takes a while to prepare the desktop, after it has logged on there's a pop up message that says that the current account is temporary and can't acces any files and the ones created will be deleted once I log off. This account is also the admin account and when installing programs a prompt comes up and ask for the password but there is none and all you have to do is press enter and it works as if you had actually input a password. Also I cannot create or delete accounts because for some other reason acces is denied, I have tried using the command prompt to change the password and tried several other commands but they don't work. I have several limitations because of this problem and it seems to keep on getting worst, any help is appreciated.

Which version of Windows 7?

I don't think the Guest account can have administrator rights, be an administrator. The actual Administrator account is hidden by default. You need at least one User set with administrative rights, shows as Administrator but others can be Standard users.
User accounts: FAQ - Windows Help
The number of Users allowed appears to be limited only by the amount of space available on the HDD.

I would enable the hidden admin account, delete any accounts you want to, then create another admin account, then disable the hidden admin account.
