Virtual machines run faster in full screen mode.
If you want your VMware Workstation virtual machine's display to fill the screen - so you no longer see the borders of the VMware Workstation window - click the Full Screen button on the toolbar. You can also use a keyboard shortcut - press the Ctrl-Alt-Enter keys at the same time.
To get out of full screen mode - to show your virtual machine inside a VMware Workstation window again - press the Ctrl-Alt key combination.
You can switch between virtual machines without leaving full screen mode by using a Ctrl-Alt-Fn key combination, where Fn is a function key corresponding to the virtual machine you want to see. To find out what function key to use for a particular virtual machine, check the title bar of the virtual machine while it is running in a window.
Note: VMware Workstation does not support running virtual machines in full screen mode on dual-monitor systems.
