"OS decides to install Candy Crush and other games I never asked for. Unacceptable. " - I would like more details on this. I don't think I've heard of that before?
Although it does not install Candy Crush, just a stub to install it, anyway, it is certainly unappealing.

All the pre-installed software is my big pet peeve for Windows 10. I don't want weather, or contacts, or xbox, or 3d builder, or email, or alarms, or skype, or office, or calendar, or groove, or money, or news, etc... I've deleted them and they just come back because of some provisioning setting.
A signature edition makes sure that the only crapware is stuff that Microsoft installed.
