There is no native Windows-based method for changing the Administrator password if you've forgotten it. The best solution available is to boot your computer with a special Linux-based floppy disk, which will allow you to change your Administrator password.

This disk may be downloaded from the Web at

If the utility asks for a registry path, it is usually winnt/system32/config. Depending on where Windows is installed, you can also try windows/system32/config, windows/system, or simply windows.

Is this the password for the built-in "Administrator" account, or simply an account you created that had Admin-level rights?
