Hi. I am using Xp Professional. When I manually edit the registry entry AutoAdminLogon to = 1 the next time I restart xp the auto logon works fine. But the second time I restart Xp AutoAdminLogon is set back to 0 and I have to click the user to logon. So I set back to 1 again and then something sets it to 0. I think this started happening about the same time AVG free did a update but not sure. I uninstalled AVG and it still acting up. Thanks for any help.
