Something odd happened after my last MS update. I have never logged on to my pc. I am the only one who uses it and its annoying to login. But now, when I boot up, there is a screen that says "Click here to login" So I click the icon that says USER, and it takes me to my desktop. It also does this when sleep mode kicks in. I checked the registry to see if anything was different. I don't see any thing. How do I stop this? I want to press the power button, and my desktop appears 5 minutes later---nothing else.
