Windows 7: Windows 7 logon not working properly

I had to do a clean reinstall of Windows 7 Ultimate and now when the welcome screen pops up I get an error stating Invalid Username or password. The only option I have is Okay. When I click okay it then pops up with my username account, not the Admin and I can key in a password and start windows. My account has admin privileges so that's not an issue but that extra step to get to my account is annoying.
Any suggestions???

during the windows setup did you enter in any admin username's or passwords? I'm not sure if 7 asks you but i know that XP did during setup. Just a thought
