When you have finished using a virtual machine in Hyper-V, what are your options for ending the session?

What will be an ideal response?

If you simply close the Virtual Machine Connection window, the virtual machine continues to run in the background, and you can connect to it later. If you use the Turn Off toolbar button, the virtual machine is powered off immediately as if the power plug was pulled, which might cause data loss or file corruption. You should try the guest OS shutdown procedure first, such as Start, Power, Shut down for Windows; the virtual machine powers off automatically when the shutdown procedure is finished. Finally, if you have Integration Services installed and the Operating System Shutdown service enabled, clicking the Shut Down toolbar button issues a shutdown signal to the virtual machine, and it automatically logs off and powers off safely.
