Don't add every App-V application to the "Open With" dialog by default
We have hundreds of published apps per user here.
One thing we've noticed is that every time a user opens the "Open With" dialog, it takes forever (3-5 minutes) to show up because it tries to populate the dialog with ALL of the currently published App-V packages. This is evident from the fact that once you expand the "More Apps" link, where you can find the names of all of the currently published packages, and from the fact that during the process, the App-V process uses up an extraordinary amount of CPU time (20-50%) and memory (several gigabytes).
This happens even though we've explicitly disabled file type associations for all of our apps by setting <FileTypeAssociations Enabled="false">.
Please either change the default behavior or provide us with some way to override it.
