Overview
During setup, the program creates a startup registration point in Windows in order to automatically start when any user boots the PC. Upon being installed, the software adds a Windows Service which is designed to run continuously in the background. Manually stopping the service has been seen to cause the program to stop functing properly. It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. It adds an extension to the user's Internet Explorer web browser. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). The software is designed to connect to the Internet and adds a Windows Firewall exception in order to do so without being interfered with. The primary executable is named dpinst.exe. The setup package generally installs about 57 files and is usually about 27.28 MB (28,603,443 bytes). The installed file yupdater.exe is the auto-update component of the program which is designed to check for software updates and notify and apply them when new versions are discovered.
