Ok- I have read every forum on this and still can't get it to work. When I go into the control center the area to expand the VM disc size is grayed out. There is a yellow warning at the top that says you need to resume the VM and then shut it down in order to make changes. So when I resume the VM and shut it down, The control center window disappears, and is not accessible. When I resume the machine- of course same error is there. I also tried through the admin tools in the start menu, but "extend" is grayed out there too. I feel like an idiot- but maybe I am not understand the VM? I can't work in Visio anymore since 64gb is not enough for me to save any more files (and I only have ten or so.
