I have Windows 7 running via Fusion on my MBP. I just ran Disk Inventory X to see how I can free up some space on my HD. Before I installed Windows 7, I had XP running. Trying to figure out why it would be showing my virtual machine taking up over 34GB. The only PC software I've installed on the virtual machine, besides W7, is Microsoft Security Essentials. Any thoughts on why so much space is being taken up? Is XP still hiding in there somewhere? If so, anyway to find out and get rid of it?
