When I removed the executable, I lost the Start menu. I guess it is a critical part of the, as the name already suggests, start menu experience. But others are more difficult to take care of, like stopping the 'StartMenuExperienceHost' service. I did so by simply removing the items from startup or uninstalling them all together, like I did with Skype and Your Phone. Luckily the list of programs/processes to kill is easily shortened. And Office 2019 also might add to that list as it is so tightly integrated into Windows 10.
The list of programs or features to kill before surround mode can be configured grows longer fast, which I guess is to be expected when using Fast ring Insider builds. This is most obvious when using the nVidia control panel to configure Surround mode.
This issue is not specific to this particular Insider build (18323), but gets worse with the increasing number of new features and improvements to Windows 10.
