Simulated enter keystroke at startup?

Hey guys, I'm running TinyXP and a linksys wusb54gc wireless adapter. The problem is linksys installs something called gtgina.dll that changes the way you log onto windows. it brings up the old style logon box, and you have to enter a password, or if you dont have one, you can just hit enter to proceed. There is no fix for this that I can find. Getting rid of the dll makes alot of stuff unstable and i get numerous error messages. Can I simulate a enter keystroke at the startup screen? Or am I going to have to deal with this at every startup?

Go to Start, Run and type in "control userpasswords2" and hit enter. Then click on the name of the user you want to login and uncheck the User must enter password check box. It will ask you for the login of said user (if there is none than leave it blank). Click ok and you all done.
