Windows 7 log in problem

Hi. I’m using an old laptop but I can’t log in. After I enter the McAffee security password, the laptop is defaulting to an old domain which is no longer in use. My username for the domain is displayed and it’s looking for a password which I can’t remember.
Is is possible to bypass this domain and simply log in to Windows? I only want to use the laptop to do some printing…
Thanks for your help.
