Automatic logon

[JeffO]

Go to Control Panel, User Accounts.
Turn off the Welcome screen and turn off Fast User
Switching.

If it still logs your account on automatically for
everyone, you need to look at some values in this key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
NT\CurrentVersion\Winlogon
AutoAdminLogon should be have a data value of "0".
If you find a value (a bit fuzzy on memory for exact name)
something like DefaultAdminPassword, then the value should
be deleted. The setting sets a plain-text, un-encrypted
password into the registry that is child's-play for anyone
to extract. Fine for home, if you like, but very bad for
corporate.
