Talk:Windows Longhorn build 4081

LH 4074 doesn't like being upgraded to LH 4081. I tried to make the Windows Classic theme to work in Longhorn 408x builds by upgrading from build 4074 (with the ComponentizedBuild registry DWORD value and set to 1) in (HKEY_LOCAL_MACHINE_SYSTEM_CurrentControlSet\Control\Windows), but it result in a file copying error. It is impossible to use the Windows Classic Theme in all Longhorn 408x builds AFAIK.
