PowerDesk von Matrox. SystemTray-Anwendung für schnellen Zugriff auf die Monitoreinstellungen.  
The file is associated with the Matrox QuickDesk that resides in your systray. If you've installed a Matrox card, you've likely installed Pdesk along with the drivers. It's a video card settings utility.
For Matrox video card.
This always crashes when I shut down my PC, i believe it also crashes explorer.exe. Dont know why this happens
Kann ohne größere Probleme daktiviert werden wenn man weder das Tray Icon noch die Tastatur-Shortcuts des Grafikkarten-Treibers nutzen will.
Not to be confused with PDesk.exe project management software!

Best practices for resolving PDesk issues

A clean and tidy computer is the key requirement for avoiding problems with PDesk. 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 PDesk.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.
