Removed features: # The Virtual Machine console is replaced by an integrated Virtual Machines shell folder. Several options from the console have been removed such as Restore at start, CPU time performance settings, muting sound in inactive virtual machines, full-screen resolution related options, configuring the host key, mouse capture options and settings for requiring administrator permissions.
# Drag-and-drop file sharing between the guest and the host
# Direct sharing of folders between host and guest operating system (Only volumes may be shared between operating systems)
# Ability to commit changes in undo disks upon turning off virtual machines (Doing so is now only possible through virtual machine Settings dialog box)
# Ability to use physical and virtual Parallel ports
# User interface controls for using virtual floppy disks (Virtual floppy disk functionality, however, is still supported and may be accessed using a script)
# Virtual PC additions for guest operating systems no longer supported have been removed. However, installing Virtual Machine Additions from an older Microsoft virtualization product works for some guest OSes.
# Properties of the Virtual Machine like Guest OS, processor, processor features, video mode, Video RAM, code cache, IDE controller reads and writes, ethernet reads and writes, video frame rate and command line options can no longer be viewed
