FIGURE 8-1 Production checkpoints, which create a full backup using Volume Snapshot technology, are<br />
new in Windows <strong>10</strong>.<br />
■■<br />
New configuration file format VMs created in Windows <strong>10</strong> use configuration version 6.2<br />
(available with the July 2015 release) or version 7.0 (introduced in Windows <strong>10</strong> version 1511) and<br />
save configuration information in a new binary file format that is more robust than the older<br />
XML-based format. The new configuration files use the .VMCX extension for virtual machine<br />
configuration data and the .VMRS extension for runtime state data.<br />
■■<br />
New security options VMs created using the Generation 2 format support Secure Boot.<br />
Beginning with version 1511, Hyper-V machines now support a virtual Trusted Platform Module<br />
(TPM), which allows for full disk encryption on virtual machines. (Note that you must enable<br />
Isolated User Mode for this option to work.)<br />
■■<br />
Hot add memory and network adapter You can adjust the amount of memory assigned<br />
to a VM while it is running, even if Dynamic Memory isn’t enabled. This option works for both<br />
generation 1 and generation 2 VMs. On VMs created using the Generation 2 option, you can<br />
also add or remove a network adapter while the virtual machine is running.<br />
■ ■ Connected Standby compatibility When the Hyper-V role is enabled on a computer that<br />
uses the Always On/Always Connected (AOAC) power model (such as a Microsoft Surface Pro 3<br />
or 4 or Surface Book), the Connected Standby power state is available and works as expected.<br />
This configuration causes power-management problems on Windows 8.1.<br />
