It seems that every time I push out a Java Update that some computers have difficulty with Java apps specifically Java Web Start Applications. It seems that .jnlp files are not getting associated with Java Web Start even though I am using the silent installation commands to associate it with IE and Mozilla so either I am missing something on my install or something else is wrong. Of course that doesn't explain why some machines are fine after the Java update and others are not.

I use Dell KACE 1000 for this distribution using the following install:

"jre-7u9-windows-i586.exe" /s /v"/norestart AUTOUPDATECHECK=0 JAVAUPDATE=0 JU=0 IEXPLORE=1 MOZILLA=1"


Any assistance or guidance on how I can force .jnlp files to Java Web Start for all users would be appreciated. I searched the registry of a machine that worked and found all sorts of keys mostly in classes_root and local machine related to .jnlp but have no idea which ones are the important ones.
