This will mean that Windows 8 users will be able to run almost every other operating system inside a Remote Desktop window, including Windows 7 and XP, SUSE and Red Hat Linux, and more (including Ubuntu) with a little hacking. At its most basic, this will just mean that you won’t have to download the free (and excellent) VirtualBox software if you want to virtualize a guest operating system — useful for power users and developers who want to try out different build and runtime environments, but not exactly a killer feature for consumers. But what if Hyper-V comes with a copy of Windows 8 (or 7) guest OS pre-installed? It would be the best security sandbox and backwards compatibility layer that money can buy."
