App-V 5.0 is a pivotal upgrade to Microsoft’s application virtualization technology. With this upgrade comes a reworked App-V package format, improved streaming, easier connectivity among virtualized applications and side-by-side support for existing 4.5/4.6 packages. Other key features include mounting of App-V applications to folders instead of the Q: drive, removal of size limitations and streamlined integration of virtualized applications with other desktop applications via extensions.
