Windows XP User Accounts Log Off/On Error

After installing Intel Wireless Drive/Program, i got this error.. Im thinking its because i selected the Single SignOn Option to be installed. Anyway, after i installed, i get the old classic looking Login/Logout Screen with drop down menu to Shutdown, etc and not the pretty Button based Shutdown. so i went to Control Panel, User Accounts and clicked no Change the Way Users Logon Logoff, and got this error

"A recently installed program has disabled the Welcome screen and Fast User
Switching. To restore these features, you must unistall the program. The
following name might help you identify the program that made the change:
iwpdgina.dll"

To fix this, download this fix. then unzip it and run the exe file located inside. It will prompt you to fix, click on Fix/Restore and try to Shutdown, it will show you the pretty screen again :P
