Can I uniquely identify a device in Windows 10/Windows 8/WinRT

Question

Is there any mechanism to identify a device uniquely (even if it is anonymous)?

To be clear, by \"device\" I mean the computer/slate/pc.

Windows 8.x

Answer 1

Could this be used as a consistent ID for the logged in user?

EasClientDeviceInformation.Id | id property

Returns the identifier of the local computer. The Id property represents the DeviceId using the GUID truncated from the first 16 bytes of the SHA256 hash of MachineID, User SID, and App ID where the MachineID uses the SID of the local users group. Each component of the GUID is returned in network byte order.
