If you want to "Put me in control of Start", how about you let me permanently kill SearchHost.exe and StartMenuExperienceHost.exe (not to mention widget*.exe) if I don't use your ad-ridden start menu (and replace it with something like Start11 instead).
These processes automatically restart if you terminate them and you can't uninstall the "CBS system app" they come from. They take about ~300Mb RAM and constantly talk over the network while providing literally no user value (I know because I suspended them and could continue using my computer with no ill effect).
