Of course on a Home Theater PC you don't want to have to supply username and password every time you start up the machine. So in order to establish that I enabled the auto-logon feature:
- Start "netplwiz" from the start menu
- In the window that comes up, uncheck the "Users must enter a username and password to use this computer".
- Click "Apply"
- A new dialog pops up in which to supply the username/password combination you want to auto-logon
- Click OK and exit.
Job done!
