I am unable to get the welcome screen on xp. It asks me to press Ctrl-Alt-Del to log in. I have tried to change the setting in the user accounts but all I get is an error message saying that a recently installed program has disabled the welcome screen and fast user switching. I haven't installed anything recently so I don't know why it has changed!! I'm sure this has been mentioned before on the forums but I cannot for the life of me find it.
