username to open and startup

Solution
Do you mean right after you turn on the computer, but before Windows starts to load?

If so then you will need to go into the BIOS menu. Below is a link to a general guide. You basically need to press down on a specific key for a few seconds like the F4, but that can vary from computer to computer depending on the BIOS being used.

You basically want to set up a password. The password should be easy for you to remember, but not so easy for others to guess what it is. If you forget your password, then you will not be able to boot into Windows (or Linux if you are using that). At that point you will simply have an expensive electronic paperweight.
