repeating ctrl alt delete on windows 7

Good Morning,

we have two windows 7 pro machines.  one was an upgrade from vista and one was a fresh install.  on both machines when you login the morning i push ctrl alt del put in my username and password and the screen goes black then comes right back to the ctrl alt del screen.  
i ctrl alt del again login and everything is fine.  

anyone ever seen this and know a fix?

thanks but none of these solutions are addressing the problem.  
it does not go to a blank screen without explorer starting.  it takes me back to the logon screen.  

LKGC will not work because it does let me logon after the second attempt.  

IT Pros Agree: AI and Machine Learning Key

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

Check the server for multiple profiles for same user.
For win7 should have the v2 ext after user

we do not use roaming profiles and locally there is only one profile for each user.  everything else looks normal.  
the odd thing is it worked for awhile then started doing this.  
Seems to be related to KB976098 back in December.
Try this option and if it doesn't work, check the event log and any *dmp files
