Hi engineers I indeed need your replies please.

Not sure what exactly are you trying to do. Is your official username and password not working? We'd also need to know what kind of operating system you have and what are the error messages the system shows. Give us all the information you can so that we can understand the problem and offer a solution.

I forgot my password and am using Windows 7Ultimate

How about password recovery that will be helpful

If it is your system then try to remove the battery of the clock and that will reset the passwords of the system

Thanks for your replies, I solved the issue using konboot.
