AppZero 4.0 is part of small list of vendors offering application isolation and encapsulation technology, which separates the application from the underlying operating system.

Users can package the application with all its relevant parts and lift it off its existing underlying operating system and link it to a similar  operating system running in the same or another environment.

Microsoft last week similar technology it is working on, but it has not announced a ship date, what the software will be called or how it will be packaged as a product.

AppZero (formerly Trigence) already has versions of its software for Linux and Solaris, but despite the 4.0 version number AppZero for Windows is the company's first support for the Microsoft platform.

With AppZero users create a Virtual Application Appliance (VAA) that basically includes all the software and configuration fields that make up the application and the associated data. The application can then be moved to another environment without the user having to write any code. The VAA contains nothing from the operating system so users don't have to consider Windows licensing issues.
