Earlier this morning I logged onto my computer by going the the welcome screen and clicking on my log on icon (no password) and I was in. An hour later I came back to log on again and nothing happened after clicking on my logon icon on the welcome screen. After looking through the help files I came across a file that says that you can make your computer more safe if you set up windows XP where you have to do a control-alt-delete which then brings up an additional logon box. I tried that and presto it worked but I don't know what changed to make me have to do a control-alt-delete before logging on. Now I want to go back to the way it was where the computer normally boots up and shows a welcome screen and displays the user logon icons and all I have to do is click on my icon and I am logged on (no password). How do I get rid of the requirement to do a control-alt-delete before being able to logon. The help files say go to control panel and then go to user accounts and then click on the Advanced Tab and then select or unselect the control-alt-delete function. Only problem is, is there is no Advanced Tab to click on. Where do I go from here? Any idea's?
