If I open up the list of running processes in the Task Manager on my Windows Vista. Then I can right-click on a process and chose "Virtualization". Not much happens after that.

What does this really do? What can I use it for?

No, it has nothing to do with virtual memory. Please read through the links that was posted in the accepted answer from 4 years ago. –  Scott Chamberlain Jul 22 at 23:25
