Problem: QT takes over and tries to open audio files such as mp3, mp4 etc, instead of WMP. I have set WMP as default player in the "Set program access and defaults"; I have made sure that file associations were done in ctr. panel -> folder options -> file types for mp3 and mp4. I have opened WMP itself and made sure that it is checked to open these files, and I opened QT and unchecked the same files so that QT does not open them. All this works for a while, until our ITS dept. runs some patches/updates and all the set up is blown again, and QT is back again in its ugly form. On some PCs nothing helps, and I am having them re-imaged. I am looking for a registry fix, so I can have it ready to correct the problem quickly since it happens often. My users have to have access to both QT and WMP. The problem is esp. bad for our teleworkers who log in onto VPN. Searching the web, I have not found any permanent solutions, so I need some help with registry fix. Much appreciate any help.
