Having installed Windows 8.1 Enterprise to trial in our environment there is an issue which stands out straight away.
When using the Group Policy 'MessageLogonText:' option, the message text is displayed at start up, even before pressing CTRL, ALT , DELETE.
The same applies when logging off a user; the user logs off, you receive the messagelogon text, and then when you click OK it goes back to the main startup screen ready to press control , alt delete.
In Windows 7 the message text is displayed AFTER pressing CTRL AT delete, which seems more logical.
Is this a fault or another microsoft whim!
