App-V Internet Explorer Add-on Conflict: Watch those Registry Keys

Students run into this problem in our App-V training classes every time.

The Problem

In one of the labs we deal with creating and deploying a handful of browser plugins in a connection group.  And everyone runs into an issue of some of them seemingly not working.  The lab specifies a set of plug-ins to use, but I usually encourage …
