I'm sharing 1 Mac with my family and using WindowsXP on Parallels Desktop for Mac. All of my family have different account on the Mac. So, I would like to switch the user automatically also in WindowsXP on Parallels. In a word, I would like to login automatically as User.A(or related user) to WindowsXP when I logged-in to Mac with 'User.A'. It is best implementation to switch to my user by using the fast user switch function if someone already logged-in to WindowsXP.
