This is the best feature in Windows 7 and Windows Server 2008 R2… period. The opportunities here are endless. So much so that I really can’t figure out how I want to use it at home. However, for my Microsoft laptop I’m using it to boot into Windows Server 2008 R2 so I can work with Hyper-V virtual machines. Yes, I could do this before, but I had to create multiple partitions guessing at their appropriate size and wasting precious mobile disk space. Using a dynamic VHD I’m able to give myself this capability and only lose 8 GB of space! Now, I’m thinking about creating an MSE demo VHD that I could use to run with the full power of my laptop.
