If your using XP there is actually a tool you can use made by microsoft to help you here. Its called tweak XP. Its in a list of "powertoys" that you see if you do a search of "XP Powertoys" at www.microsoft.com
Using this, you not only set it to load yours up automatically, but if you did happen to ahve a password, you chould enter it and still have your account load up when you turn on the computer.
 found the link with all the "toys" for you. http://www.microsoft.com/windowsxp/d...powertoys.mspx
there's actually quite a few usefull things on there. I find the graphing calculator to come in handy at times, even if it is kinda hard to use.
