I am not expert but maybe I can help.
Most start ups are listed in Bleeping Computers Start Up Programs database.
Couldn't find dtingq.exe and it did not show up in a Google search. Google search can find a lot of start ups. Be careful of the source as a lot of links will tell you a legit start up may be malware and to run there special scan so they can sell you software that sometimes is malware itself.
Unless you really know how to work with the registry I would get help here before making any registry changes and always, always, always back up your registry before making any changes.
Revo Uninstaller seems to do the most complete job to uninstall program traces when you select the most thorough removal options but of course it is slower to do this. The program has to be installed to use it and I have had to reinstall programs and use Revo for a more complete install on occasion. I use this when I am concerned about program traces being left. Whether it is more effective for registry items I am not certain but I have never had a problem with registry items left when using Revo.http://www.revouninstaller.com/revo_uninst...e_download.html
Hope this helps
