Dedoimedo posted a review of Prayaya V3, a portable virtual operating system for Windows, which lets you run a separate Windows environment on top of existing Windows installation in an isolated container.

Prayaya V3 is a portable virtualization software for Windows, which lets you create and run a virtual operation system on an external device. The goal of the software is to provide you with flexibility and portability without compromising your security and privacy.

This concept is very similar to Mojopac, a product which I've reviewed in the past. Mojopac was a very handy and useful product, allowing you to run software from external devices without touching the underlying operating system. However, Mojopac has since been discontinued. This makes Prayaya into a good candidate for portable virtualization.

Let's see what Prayaya can do.
