Disable display of status messages

If you don't want your XP computer to display the logon, logoff, startup and shutdown status messages, you can turn them off by editing the registry. First be sure to back it up, then perform these steps:

Open your favorite registry editor.
Navigate to HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ policies \ system
Right click in an empty space in the right pane, select New and select DWORD value.
Name the new value DisableStatusMessages.
Double click the value and give it a value of 1.
