Having disabled sdmcp.exe via Stardock Central a long time ago, a recent slew of updates through *Impulse* has re-enabled it. The update affected WB6, SKS6 Pro, IP4, MyColors Diamond and (maybe?) DesktopX.
SDC is still installed, but I never use it anymore. Currently active Stardock apps include CursorFX, WB6, IP4, ODPlus, SoundPackager and 3 stand-alone DesktopX Gadgets.
Why? How?
