This has been a recurring issue with PowerDVD 13 since it was released. Here is the issue:

I use PowerDVD to play DVD and BluRay movies only. I do not use it to play audio, because I have other software that specializes in that. The trouble is that PowerDVD forces itself as default Windows player for almost all audio files. I understand this happening on the initial install of the program; however, it does this over and over with the install of every update! Can you please stop doing this when installing updates? My configuration had already been set for file associations. Why is this being lost when I install an update?

I hope this gets resolved quickly.

Thank you.
