Programatically detect if VT-x or AMD-v is enabled on Windows
virtualization, windows
Solution
I believe the best bet to check if virtualisation is enabled is by using WMI and check the Win32_Processor class. The value of the "VirtualizationFirmwareEnabled" field should give you if it is enabled.
I have tested on my machine by enabling and disabling in the BIOS and this value appears correct.

For checking what is supported I believe you will need to use the __cpuid() intrinsic function with an Information type of 0x1 and 0x80000001 to query the CPU features. Examples can be found on the following links.

Problem
On OSX or linux, it is rather trivial to view CPU capabilities in the terminal. Is there a way to access the CPU information, specifically the hardware assisted virtualization capabilities, on Windows? I only found Microsoft's tool: http://www.microsoft.com/en-us/download/details.aspx?id=592 but would like something that doesn't require additional binaries.
