Snapshots may be taken of a virtual machine using a number of different approachesusing either the ''Hyper-V Manager'' or the ''Virtual Machine Connection'' tool. From the Virtual Machine Connection tool window click on the ''Action->Snapshot..'' menu option, or click on the snapshot button located in the toolbar. Alternatively, launch the Hyper-V Manager (''Start->Administrative Tools->Hyper-V Manager''). Once launched, right click on the virtual machine for which the snapshot is to be taken and select ''Snapshot'' from the popup menu. Snapshots may also be triggered by selecting the desired virtual machine from the Hyper-V Manager list and clicking on the ''Snapshot'' link in the ''Actions'' panel. When a snapshot is taken from the ''Virtual Machine Connection'' tool, a dialog will appear while the snapshot is in progress providing the option to give the snapshot a name other than the default name. If no snapshot name is given, or any of the other methods of taking a snapshot are used, the default name of the snapshot will be constructed using the name of the virtual machine combined with the date and time that the snapshot was taken. Whilst the snapshot is being taken, the ''Operations'' entry for the virtual machine will in the Hyper-V Manager will display ''Taking snapshot'' together with a percentage value indicating the progress of the snapshot process. == Hyper-V Manager Snapshot Trees == Snapshots taken of virtual machines are presented in Hyper-V Manager in the form of a ''snapshot tree'', with one tree for each virtual machine. Each new snapshot taken of a virtual machine is added to a new level of the tree for that machine. A typical Hyper-V Manager snapshot tree is illustrated in the following figure:  [[Image:hyper-v_snapshot_tree.jpg|A Hyper-V Manager virtual machine snapshot tree]]  If the selected virtual machine is currently running, as is the case in the above illustration, an additional tree entry in the form a a green arrow and the word ''Now'' represents the currently running virtual machine. Right clicking on this tree item provides options to connect to, or access the settings of the virtual machine.  As each snapshot in a tree is selected, the panel beneath the tree panel will update to display additional information about the snapshot together with a thumbnail screenshot of the virtual machine's console at the point the snapshot was initiated. The following figure shows a typical detail panel for a snapshot:  [[Image:hyper-v_snapshot_details.jpg|The Hyper-V Manager snapshot details panel]] == Managing and Applying Virtual Machine Snapshots ==
