I cannot remember my password for my windows vista home premium account i don't know how to get in it. please help! i did not make a recovery disk:(

Is there any other administrator account? Please check if this is an OEM version. If so, please try to boot into Safe Mode to check if the built-in administrator account is enabled there. If the built-in administrator is disabled and no other administrator account can be logged in, then we have to reinstall the system after backing up the important files with Command Prompt. However, if you've forgotten your Windows password and you're on a domain, you may contact your domain administrator for it or remove the computer from domain and create an administrator account, then re-join domain for this issue.
