how can i get lost pass code for laptop if i can not remember it?

I have a Dell Inspiron notebook. I changed my pass code to log onto notebook two weeks ago. I thought I could remember pass code and did not write new code down. I need to know how I can retrieve Microsoft pass code if I did not make note of new code. Is there a software that I can use?

I'm not sure about Dells, but I know that on Toshibas there is a hidden partition that you can access and restore to factory setting. Look around on Google, see what you can find.
