You can install, upgrade, and modify VMware Tools in virtual machine guest operating systems.

VMware Tools is a suite of utilities that you install in the operating system of a virtual machine. VMware Tools enhances the performance of a virtual machine and makes possible many of the ease-of-use features in VMware products. For example, the following features are just some of the features that are available only if VMware Tools is installed:

Significantly faster graphics performance and Windows Aero on operating systems that support Aero

Copying and pasting text, graphics, and files between the virtual machine and the host or client desktop

Improved mouse performance

Synchronization of the clock in the virtual machine with the clock on the host or client desktop

Scripting that helps automate guest operating system operations
