On the Altiris Juice community popped up since a while a great utility for Software Virtualization Solution (SVS) 2.0: Software Virtualization Trinket.
It allows users to activate, deactivate or import new applications via system tray.
It’s nothing special but I believe it makes so clear how immediate can be enable or disable a virtualized application, and how simple can be having several versions (even betas) of the same application ready to be launched in the same system.
