We are running Windows Server 2008 Standard Edition, with Windows XP Professional on our workstations.
I have created a few Organisational Units and put various levels of user in each. I have also created a GPO that I have link to each of the OU's. Everything is working exactly as it should with one exception: all users now have the classic start menu rather than the standard one. Even brand new users that are created.
I have checked that the "Force classic start menu" option is disabled, and also that the Start Menu preference hasn't had any start menu's added to it.
I did a quick search which turned up this link:
If I follow the guide and create a registry entry in the GPO to update the value, the start menu switches to a single column with a solid black line on the left the full height of the menu. It also adds My Computer back to the desktop which has been removed by the GPO. As soon as I delete the new registry update the start menu goes back to the classic two column menu.
When no one is logged in, the login screen appears in the standard theme - as soon as you login the theme is removed and the classic styles shows.
