I know that this is just Microsoft trying get user feedback but because it's Microsoft, it still seems bad. It's just seems so disingenuous when a company like Microsoft, that usually ignores all user feedback, tries to get user feedback for a product that, if they actually listened to user feedback, they would already know that a majority of Windows users don't want.
You could also open its executable with a hex editor and mangle its header. That'd sure keep it from running, regardless of what anyone else on the computer fiddled with. Or being "helpfully" relaunched by the system, despite your efforts.
Not sure if Windows Update would notice and overwrite the file. Maybe after you do this, mark it read only.
