I used the DISM /online /Set-Edition:ServerEnterprise /ProductKey:489J6-VHDMP-X63PK-3K798-CPX3Y to upgrade a couple of my servers to the enterprise edition of 2008 R2. After a reboot the 2 of the 3 servers have a "Classic View start menu" I want the normal 2008 / windows 7 look how do I change it back?
