Xbox.TCUI - that sounds like a Windows question, I don't know the answer, if you see that I should fix something about it, let me know what.
boot.wim processing - You can select yourself on the Apply page - Image tasks what applies to which edition, make sure boot.wim editions are not selected. I'm guessing you are talking about integration.
You can prevent the backup of the preset to the ISO root by selecting "Don't backup preset" on the Apply - Image tasks.
As for local presets folder, that cannot be disabled, BUT you can disable auto-loading of last preset in File - Settings.
