Hi guys,

I'm working on creating a guide to make an invisible VM on Windows (i.e. run a VM in the background without having to worry about the the window on your taskbar or anything). It's certainly a work in progress, and I'd appreciate any feedback on it. Does it work? Anything need clarification? Let me know.

It's located at http://invisiblevm.sitepages.org/

Thanks!

Check the forum here. There is even a sticky post with your idea. It's called "Run a VM as a service".
