Some useful utilities if you struggle with username password at login on windows

Rohos Logon Key. It converts any USB drive into a security token for your computer and allows to access Windows in a secure way by USB token, replacing the Windows login. I have tried this using a single, local profile and it works well. It’s functionality can be extended to logoff/shutdown etc when the drive is removed and it also supports Bluetooth devices. There is a server version for deployment within Active Directory.

Rohos for the Mac

Rohos for the PC (windows)

Dekart Logon. A smart card or USB drive is used to unlock the computer when it boots and lock it whenever it is left unattended. Similar to Rohos, but uses proprietary hardware to create an additional security layer. Also support Active Directory environments and biometrics (except Vista)

MatchLogon. Allow any hardware device or method of authentication (USB Tokens, Biometrics, smartcards etc) to integrate with the Windows Logon process.
