The charger for my laptop has broke, so I'm using my very old PC for a few days. This computer has two accounts - mine, which is the administrator account, and another, which is a standard account. I put a password on the admin account a few months ago, and now it's expired. I don't have the password reset disk to change it, so I can't get into the account at all. I can't change the password through the standard account, and I can't change the standard account to admin. I've tried everything I could find on the internet - booting in safe mode, running command prompt as administrator and entering various commands, enabling the built in administrator account in different ways, and none of them worked. I also don't have the Windows 7 disk.
Any suggestions would be welcome, as soon as possible! If you need more information, feel free to ask. Thanks.
