Hope this helps...   I managed to get around the need by turning off the Ctr-Alt-Del requirement for Login.  To get to that toggle you can open the Control Panel, click User Accounts, then click User accounts again, then click Manage User Accounts.  This will open up a new window.  In the User Accounts window, click and choose the Advanced tab.  On this tab is a check box for Require users to press Ctr+Alt+Del.  If you uncheck that you'll be all set.

Least, that's what I've done.....

Edit: This is for Windows 7.  The setting will probably still be there in other versions, but probably in a different place.  If nothing else you can find in all versions a Local Group Policy that will do it.
