it is a part of desktopx software
Because I wrong uninstalled DesktopX , it's make my Start panel freez. I have to shut it down manualy everytime after logon.
I believe it's harmless but still annoying. I mean all you have to do is open task manager and end it. That's if you are using any stardock product if not then definetely go to C:program files/common.../stardock and delete the folder
Its part of's software, used in ObjectDock, DesktopX, IconX, it is a required file if you have them.

Occationally spawns update.exe. I hate automatic updating of anything, however this is part of Stardock Central so it's harmless unless exploited.
Its a Stardock app
SDMCP internally populates a list of System Tray and Taskbar entries, which is queried by ControlCenter, DesktopX, ObjectBar, ObjectDock, RightClick, and maybe others. Removal of this file will not cease function in these applications, but will negate the systray/taskbar feature. To safely shut this down, copy/paste this into Start- Run: [ "%commonprogramfiles%\stardock\SDMCP.exe" -shutdown ] (Without the [ ])

Best practices for resolving SDMCP issues

A clean and tidy computer is the key requirement for avoiding problems with SDMCP. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the SDMCP.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan.
