How to hide VirtualBox menu and status bars

VirtualBox machine window is adorned with menu bar at the top and status bar at the bottom. You can hide both to save on valuable disk space.

For Windows XP Desktop (Host):

• If not already, add VirtualBox executable path to your %PATH% environment variable in Windows:
• Bring System Properties dialog with My Computer->Properties->Advanced
• Click on Environment Variables
• Edit Path system variable and add C:\Program Files\Oracle\VirtualBox path. 

• Under Windows:
• From Start button, run 'cmd' command to open command shell.
• To modify global configuration settings of the VirtualBox, type in the command:

C:\> VBoxManage setextradata global GUI/Customizations noMenuBar,noStatusBar

When you restart next time your Guest Virtual Machine, you should get optimized view.

To bring back the menu popup, press the Host key and Home key. My Host key is mapped to Right Ctrl, so the combination would be {Right Ctrl}-{Home}.
