Ulead Burning Helper. I stopped it, cause for me is it only annoying process in TaskManager.
Believe to cause random BSOD on Win 7 64 bit. Agree that it may be related to WinFast DTV1000S. Removed ULCDRSvr.exe; seems to solve BSOD but Event Viewer shows that it wants to load; not sure which application wnats to load it.

Best practices for resolving ULCDRSvr issues

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