Concerning the System-explorer settings : they are disabled similar to your picture. They are even disabled automatically because "not supported on removable disk"
Concerning process-list : see the two pictures :
- picture 1 is before launching System-Explorer
- picture 2 is after launching System-Explorer from the Liberkey-Menu
I checked the Liberkey-menu : SystemExplorerLKL.exe is used
As I wrote earlier, this same Liberkey-setup was used in WindowsXP without any problems !
