How do I change a Standard user to Admin (Windows 7)?

Question

I have a Compaq Presario laptop with Windows 7 on it and I have two accounts on it: Me and my mum's.
The problem I have is not having an Administrator.
Everytime I want to run a program as Admin, I get this message within the UAC (User Account Control): "Geef een administratorwachtwoord op en klik vervolgens op Ja om door te gaan." (In English: "Enter an administrator password and then click Yes to continue.") but there's no field / space I can type in anything and the "Yes"-button is blocked (grey & not able to click on)
This sucks cos now I can't run any programs as Admin, I can't install anything new and it's keeping me from changing my laptop's default settings.

Someone please tell me how to change the account from a Standard user to Admin without having to re-install Windows 7 (I don't even have the CD-rom). I've already tried using Command Prompt but I can't run it as Admin otherwise I get the damn UAC again. I don't know if once I use the Advanced Recovery Method #2 (Recover to manufacture's settings) I will still have the manufacture's installation files on my drive (like when using a laptop for the first time; you get a menu to configure / install Windows without the CD-rom).

More info on my laptop:
OS: Windows 7
Accounts: 2
Family Safety: ON (only on my account, not my mum's)
Accounttypes: Both are Standard users

Please help!

Answer 1

just go in your control panel - security - modify account and change to administrator unfortunately this will require the true admin password - you do this by rebooting and upon boot up click your f8 key and go down to safe mode when it comes up it should give administrator as a option.

ok so your objective is to clearly circumvent your parents access

you can boot a live install of linux and edit the ntfs file permissions.

you could risk data loss though

you can dump the registry hives and extract your parents password

lopht crack might even do the job. not sure never tried it on a standard user account.

Answer 2

You cannot have an administrator account under parental controls.
