Maybe I don't take too much notice, but this is the first I'd heard of this feature in windows 10.

I just enabled it and then ran the Debian installer. Took all of 10mins. The Debian OS mounted all of my drives, sees all cores and memory and can see everything as far as I can tell.
Now to try BOINC.
Seems like a native VM. Might be good for people who don't want to have the hassle of a dual boot system.
