After 3 hours of searching I have finally come across this - http://blogs.technet.com/b/mrmlcgn/archive/2013/02/26/windows-8-associate-a-file-type-or-protocol-with-a-specific-app-using-a-gpo-e-g-default-mail-client-for-mailto-protocol.aspx
http://technet.microsoft.com/en-us/library/hh825038.aspx So it would seem that you need to create an exported xml file which you can apply with group policy. Scripted changes to the registry no longer work for Windows 8 file types as there is a hash check in place. Not sure if it will work or not - am going to have a go in the lab this afternoon. I have been unable to find a posted power shell script option - although I'm sure they exist.

Some of the file types I'm referring to are .mp3 .wav .wmv .jpg .bmp etc. It's our preference to have these open using Windows Media Player or Windows Picture Viewer. I can set the file associations on a Hyper V base image but when I run sysprep and set the copyprofile option to true in the unattend.xml it resets these settings back to default. I don't mind this occurring on say a Surface Pro which is a tablet and a user may want to take advantage of the modern apps, but for our desktop users it not really appropriate as the Modern/Metro Apps don't always integrate/communicate with some of the traditional desktop apps. I'm finding that our users are having consistently swap between the Modern UI and the traditional desktop or we are been asked to make the change in file associations for them.
