Disable the Welcome screen in Windows

The welcome screen is something I find annoying - I don't really like the look of it. A good enough reason to disable it then! To turn it off, so that you can log on and log off using the classic login prompt:

1. Open the Registry editor (Start->Run->Regedit) and go to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\Current Version\WinLogon 
2. Change the value for LogonType, from a "1" to a "0". you can guess that 0 gives Classic Mode and a 1 shows the Welcome Screen.  If there is no LogonType key, add it manually as a String-type key.
3. Exit the registry editor when you are finished.
4. Restart and you should be done.

Note that you must be an administrator on the computer / domain to make these registry changes.
