I think at least some of you might have started using Hyper V.
Did you feel how difficult to move from your Host Operating System (OS) to Guest OS (You have to click some keyboard combinations to move in and out).
To make our life easier you can install HyperV Integration Services to the guest OS.
To install, after starting your virtual machine click on the Action menu and click Insert Integration Services Setup Disk. This will start the installation process. After this finishes you no need to click key sequences to go back and forth among the OSs.
This will also install the required components so that the virtual machine will be able to communicate with local area networks and internet.
Please note that you need to install the Integration Services in each and every virtual machine separately.
