I am actively against Windows 8 in a Domain environment as the system has severe permissions issues for workstations with multiple users. It seems that the first user to install items, create directories, etc. becomes the overall master of them and this makes even basic SysPrep difficult. I am tearing my hair out trying to get terminal servers and cloning projects done, stuff that was a breeze on Windows 7 in comparison. I wish Microsoft was smart enough to differentiate between their home consumers and their business consumers.
