iCore Virtualized Desktops for Windows

I've just found note about free sandboxing software to isolate risky behavior.
And i want to discuss new interesting free software iCore computer 3-in-1.
It allows to create multiple virtualized desktops.
Each Virtualized Desktop is an isolated virtual machine that is associated with own user account.
All such virtual user accounts are isolated from each other and host( from their web site).
So I tried to infect one of the VDs through visiting porno sites))) It seems that others and host stayed clean!
But I can't install drivers inside iCore.

From wikipedia:
"It is an OS level virtualization for Microsoft Windows.It still in beta. http://icoresoftware.com/ "

Any thoughts?
