XP Pro...login user screen

[Spydermag68]

I just did a clean install of XP Pro (Free from M$ .net. Thanks Hot Deals) on my computer about a week ago and for about a week I could turn on my computer, get something to drink while it was booting and come back to see the computer is ready to run from the desktop. Now after I installed Visual Studio .net I come back to see an icon of chess peice that I have to click to finish booting up. Is there a way to get rid of this "login screen"?
