The built-in way is not exposed to users via any nice interface, but it's simple enough to do it yourself -- I wouldn't describe it as a "hacker-way".
If you want the user/pass/domain style, you can get that by enabling the group policy setting for "do not show last username". If you have Windows 7 Pro, Ultimate or Enterprise, you can change it by opening gpedit.msc from the Run box, and navigating to Computer Configuration > Windows Settings > Security Settings > Local Policies > Security Options, and finding "Interactive logon: do not display last user name". If you have Windows 7 Home, you will have to change it in the registry by going to
HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System and changing the value from 0 to 1.
