VMware Workstation features the ability to run multiple operating systems on the same PC without the need to partition the hard drive, or rebooting. It allows users to interoperate among each of these operating systems, including full networking, device and file sharing, and cut-and-paste capabilities, and undo changes made in a given session.
This beta build contains no new features but many bugs have been fixed.
