SHELLSTATE structure is wrong, old, incompatible

According to registry (HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer), sizeof(SHELLSTATE) must be 36 in Win2k3. The registry value ShellState and the SHELLSTATE structure are different in size and layout. The current SHELLSTATE is wrong, old, and/or incompatible (to be retested!). We have to check whether the binary layout of SHELLSTATE is correct on both of MSVC and GCC.
