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 />
