Forgetting your password can be a frustrating experience, especially when you don't have a reset disk or can't access safe mode. But don't worry, there are still some methods you can try to reset your password without the need for additional software:

1. Use another Admin Account: If you have another admin account on the same computer, you can use it to reset the password for the account you're locked out of.
2. Offline NT Password & Registry Editor: This free software can help you reset your password by editing the Windows registry offline. You will need to create a bootable USB or CD to use this tool.
3. System Restore: If you have a system restore point set up before you forgot the password, you can use it to revert your system to a previous state when you knew the password.
4. Contact Support: Some manufacturers provide a way to reset your password by contacting their support team and verifying your identity.

Remember to create a password reset disk once you gain access to your account again to avoid this situation in the future. It's essential to stay proactive about managing your passwords and security to prevent any unauthorized access.
