How to make VMWare Workstation use multiple windows for VMs instead of tabbed display?
Solution 1:
Just drag the tab out of the VMWare window and take it to the other monitor. If that's what you mean. It will create a new solitary window with the other running OS in it. Have done that on Ubuntu, and it should work the same for Windows 7.
NOTE: the dragging action only works if the VMware window is not in full screen mode.
Solution 2:
Execute another window from VMware main menu: File -> New Window
