Password log-in- disabling
Start > Settings > Control Panel > Passwords and tick the little button which says "All users use the same preferences", click OK and you should be asked to re-boot, do so. When you have re-booted the Log-on box will appear again, this time enter your name but don't enter a password leave it blank, don't even click on the password field, then click OK (NOT Cancel)and Windows should load. Now go to Start > Shutdown and re-boot again. This time the Log-on box shouldn't appear.
In Control Panel > network properties: Make sure the logon type is set to "Windows Logon"
Do a search for *.PWL and delete all results
Delete "C:\Windows\Profiles" folder
