Okay, I see.
Well in that case, you really only have to options.
The first would be to try to bypass the password, which will most likely require the use of free third-party password ***** software. As I say, the software itself is free, but it will require that you create a bootable recovery disc. This isn't especially difficult, but it will require that you have access to a blank disc and CD/DVD burner.
I will point you toward the following article:
This article essentially lists every known method for bypassing/resetting a password ***** Windows 7, with links to full instructions for each method. You can look at each method listed, but most likely the one you're going to want to focus on is the one titled, "Hack Your Windows 7 Account with a Password ***** Program."
If none of the methods listed in this article work for you, then your only remaining option would be to purchase an original Windows 7 installation disc from somewhere like eBay and reinstall the operating system from scratch.
One of the above options should do it for you. If you have any other questions on this, just let me know.
