A. One of the great features of virtualized applications with App-V is the ease of updating them. Instead pushing application updates to every desktop, you just open the existing virtualized application in the App-V sequencer for update and apply the updates. Those changes to the virtualized applications are pulled down by App-V users the next time they launch the applications.
If you select a custom installation during the update, the Installation screen shown below will have a Run button to launch updates.
