The idea of portable application is that they don’t need any installation, they don’t add anything to your registry and they don’t install any new services or drivers. We can run the program, just by double-clicking it and to uninstall the program, just delete the file(s) that make up the application.
Difference between Portable Windows and portable Virtual Windows is:
Portable Windows: You would need to boot from the USB thumb drive which has the Windows 8.1 already installed, allowing you to use just one operating system. Also you would need to change the boot sequence to be able to successfully boot from the USB, which can be rather difficult doing on someone Else’s Computer.
Portable Virtual Windows: No need to change the boot sequence, it can be run on any computer with an already running Operating System, it can handle multiple Operating Systems virtually, and all we need to be careful is that the external drive adopts the same drive letter when plugin it to a computer system.
