Since I installed Galactic Civilizations II, or probably already when I installed Stardock Central, there is a process called sdmcp.exe running on my computer. Searching for it on Google reveals it is a part of "Stardock Personalization Software". I'd like to decide when to run Stardock Central myself, rather than having it run at boot time, so I've been searching my registry and startup locations in the start menu, finding no trace of it. Hijackthis reported a dll under Program Files/Common Files/Stardock being run at logon time through some obscure method, and using Hijackthis to remove it does in fact stop the process from starting at logon.
What is this process doing when it is running, and why have you hidden it?
