CDASrv.exe gehört zur Printersoftware "Easy Printer Manager" von Samsung und wird bei der Installation von Samsungdruckern (auch Name Xerox) automatisch installiert. Es legt eine Vielzahl von Dateien an. !!!!! Es Verzögert den Windows-Start und das Herunterfahren.

Wurde bei mir zusammen mit dem Treiber meines neuen Druckers "Samsung CLP-365" installiert: C:\Programme (+ Programme (x86))\Common Files\Common Desktop Agent
Installed as part of Samsung Easy Print Manager
I also have a Samsung printer for more than a year. A weeks ago, together with the update to Windows 8.1 my keyboard input was slow. After a long search it appeared that CDA server was causing this. I disabled it in the Windows startup settings. I can not remove it through the control panel, because it is not mentioned there. I could remove the files of course, but for now all works fine.

Best practices for resolving CDASrv issues

A clean and tidy computer is the key requirement for avoiding problems with CDASrv. 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 doing a repair of your installation, or in the case of Windows 8, 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 CDASrv.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.
