Windows stuff

Create auto-logon for a particular user on an XP machine:

in regedit:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

and if not present create these two keys:
- "DefaultUsername" (type REG_SZ/string), value is the username you want to logon
- "DefaultPassword" (type REG_SZ/string), value is the password you want to logon.
- "AutoAdminLogon" (type REG_SZ/string), value "1"

Since the password is visible in plaintext it's not really a good idea to auto-logon an administratative user, but something like a guest/restricted user would be fine - e.g. just to operate a game dedicated server or a torrent downloading machine, but unable to make system changes.
